11 Things Contact Lens Wearers Should Never Do

More than 30 million people in the U.S. wear contacts, but that doesn’t necessarily mean they take care of them quite as carefully as they’re supposed to. If you’ve worn contacts all your life and have never gotten an eye infection, you may think you’re a pro—but you’re probably putting your eyes at risk in at least one way, if not more.

Studies routinely find that eye patients don’t take care of their contact lenses exactly as they should, and may not even know they’re slacking. One 2011 study found that 85 percent of eye patients surveyed perceived themselves as compliant with the proper contact lens care practices, but in reality, only 0.4 percent were fully compliant. (The study was comprised of just 281 people, so that meant only one single person followed the proper procedures.)

There are plenty of ways you can put your eyes at risk when you wear contact lenses, some of which you might not even realize are dangerous. Here are 11 things you should never do with your contacts.

1. DON’T LET THEM COME INTO CONTACT WITH WATER …

The water in a swimming pool, a lake, the ocean, or even inside your home isn’t sterile, and that can mean bad news if that water gets under your contacts. People don't “really realize it could be a sight threatening move” to swim in contacts, optometrist Ceri Smith-Jaynes, a spokesperson for the UK-based Association of Optometrists who has been practicing for 20 years, tells Mental Floss. And it's not because they might float away: Soft contacts can change shape when wet, which can sometimes cause micro-abrasions on the cornea. And if that's not horrifying enough, there's an amoeba called Acanthamoeba that can live even in chlorinated water—and if it gets under your contacts, it can use the micro-abrasions to burrow inside your cornea, causing infection.

While rare, the infection is notoriously difficult to diagnose, and you can eventually lose your eye. (Smith-Jaynes just saw her first case of it in her professional career—the woman is expected to be fine, but had to spend weeks in the hospital putting in eyedrops every hour.) And even if you aren’t exposed to Acanthamoeba, there can still be other germs in water that contact lens solution can’t kill, so if you do break the rules and take a dive in your contacts, you should throw those lenses out immediately after. If you’re a passionate swimmer, you can always get prescription goggles.

Yes, your optometrist knows you probably go to the swimming pool and the beach in your contacts, despite their warnings. “I know my patients do it,” Smith-Jaynes says. “I’ve actually bumped into [a patient] and they recognized me—and they shouldn’t have, because I know how short-sighted they are.”

2. … SERIOUSLY, ANY WATER. OR ANY OTHER LIQUID, FOR THAT MATTER.

That means you should only touch your contact lenses if your hands are completely dry. In general, don’t let anything touch your contacts that doesn’t explicitly state it’s made for contact lenses. Saline solution won’t cut it, and neither will regular eye drops. Stick to solutions and drops that explicitly say “for contacts” on the bottle.

3. DON’T PUT THEM IN BEFORE YOU START YOUR MORNING ROUTINE …

As nice as it is to be able to read the shampoo bottle, you shouldn’t put your contacts in before you shower or wash your face, because—you guessed it—of the risk of exposing your lenses to tap water. You should also wait to put them in after you blow dry your hair or apply hairspray, because those can dry out your lenses.

4. … BUT DON'T WAIT UNTIL AFTER YOU APPLY MAKEUP.

You should put your contacts in before you put on your makeup, or risk damaging your lenses. If you have any makeup residue on your hands after you finish perfecting your eyeliner or contouring, and then you put in your contacts, you could get that on your lenses.

Avoid waterproof makeup, because if that gets on your contacts, the oils in it can’t be washed away by blinking. That could potentially cause your contacts to blur or damage the surface of the lens. Even if you wash your contacts with solution later, contact solution isn’t designed to clean up those types of oils, and it may not entirely remove them.

Wearing contacts may also inhibit certain looks, unfortunately. You shouldn’t apply mascara all the way from the base of your lashes up, since you are more likely to get makeup in your eye that way. Instead, apply it from the midway point. And you shouldn’t use eyeliner on the inner lid of your eye. Apply it to the skin above your lashes instead.

5. DON’T SLEEP IN THEM (UNLESS YOUR DOCTOR SAYS IT’S OK).

Sleeping in your contacts can lead to infection, too. Most contact-wearers know whether or not they’re allowed to sleep in their specific lenses, but you might not realize how risky wearing non-approved lenses to bed can be. “You’re greatly risking your sight” by sleeping in a lens that’s not approved for overnight use, Smith-Jaynes says. Because you don’t blink in your sleep, tears aren’t washing under your lenses, and your eye isn’t getting enough oxygen, both of which make it easier to get an infection. Sleeping in your contacts can lead to complications like corneal ulcers or a condition known as Contact Lens Induced Acute Red Eye (CLARE).

6. DON’T PUT YOUR DIRTY HANDS ON THEM.

You shouldn’t stick your dirty fingers in your eyes, period, but you definitely shouldn’t touch your contacts with them, for all of the usual reasons involving bacteria, oils, and other gross, damaging substances. You should always wash and dry your hands thoroughly before you touch your lenses.

7. DROPPED YOUR CONTACT? DON'T PUT IT IN YOUR MOUTH AND THEN BACK IN YOUR EYE.

Every once in a while, one of your contact lenses might come out in a public place, but you really shouldn’t root around on the floor trying to find it and put it straight back in—even if it means not being able to see for a while. If you do find the missing lens, don’t rinse it with tap water, and definitely don’t put it in your mouth. Ideally, you should just throw it away. To stay on the safe side, carry around an emergency pair of glasses or pair of disposable lenses in your bag or your car, or stash them in your desk at work.

“Most soft lenses are monthly or daily disposable so, if this unlikely event happens, you’re better off disposing of it and opening a new one,” Smith-Jaynes says. “It’s not worth trying to be thrifty here.” If you wear hard lenses and can’t throw them away immediately, inspect the dropped lens very carefully for scratches. If it looks like it made it through unscathed, you’ll want to disinfect it fully, including rubbing and rinsing it with solution and letting it soak overnight, before you think about putting it back in your eye.

8. DON’T WEAR A RIPPED LENS.

Besides being terribly uncomfortable, there’s a more serious reason to immediately toss a torn lens, even if it means being unable to see for the rest of the day. The jagged edge of the ripped lens can scratch your cornea. And because the lens won’t hold its regular shape, it won’t fit against your eye the same way, and is more likely to move around and possibly tear further, leaving you with bits of contact lens in your eye.

9. DON’T USE THE SAME CASE FOREVER.

You should be as careful with your lens case as you are with your contacts themselves. In order to minimize the bacteria and fungi that build up on the case, you need to rinse it out regularly with solution, then leave it open and upside down to dry fully. Whatever you do, don't rinse out your case with tap water—that has been linked to that nasty Acanthamoeba infection—and don't rinse out your case and then close it right back up without allowing it to dry—that creates a wet, dark environment for bacteria to grow (especially if you're using something other than solution). By the time you get back to it, it will be dirtier than it was before you rinsed it.

Even if you’re taking good care of your case, you need to toss it and get a new one regularly. If you change your lenses monthly, you should change cases then, too. After that, lens cases can start to develop a biofilm of bacteria and fungi, and if you store your contacts in there, you’re putting yourself at risk of infection.

10. DON’T WEAR THEM FOR TOO LONG.

Just because you can still see clearly out of your contact lenses doesn’t mean you should can keep using them for longer than you’re supposed to. If you wear your daily-use or weekly-use contacts for a month, it can, in the worst cases, lead to serious complications like scarring of the cornea and loss of vision. Daily disposable lenses, for instance, are made of a thinner material than contacts designed for longer use, and they're not made to allow the right amount of oxygen and moisture into your eye for an entire month. The few dollars you might save by not opening a new pack aren't worth the damage it can cause.

11. DON’T WEAR THEM WHEN SOMETHING IS WRONG.

If your eyes feel uncomfortable, don’t power through it; go see your doctor. If you notice any pain or redness in your eyes, take your contacts out and consult an optometrist. You don't want to let a serious infection go unchecked.

Now more than ever, it’s important to have a good hobby. Of course, a lot of people—maybe even you—have been obsessed with learning TikTok dances and baking sourdough bread for the last few months, but those hobbies can wear out their welcome pretty fast. So if you or someone you love is looking for something that’s a little more intellectually stimulating, you need to check out the Flybrix LEGO drone kit from Fat Brain Toys.

What is a Flybrix LEGO Drone Kit?

The Flybrix drone kit lets you build your own drones out of LEGO bricks and fly them around your house using your smartphone as a remote control (via Bluetooth). The kit itself comes with absolutely everything you need to start flying almost immediately, including a bag of 56-plus LEGO bricks, a LEGO figure pilot, eight quick-connect motors, eight propellers, a propeller wrench, a pre-programmed Flybrix flight board PCB, a USB data cord, a LiPo battery, and a USB LiPo battery charger. All you’ll have to do is download the Flybrix Configuration Software, the Bluetooth Flight Control App, and access online instructions and tutorials.

Experiment with your own designs.

The Flybrix LEGO drone kit is specifically designed to promote exploration and experimentation. All the components are tough and can totally withstand a few crash landings, so you can build and rebuild your own drones until you come up with the perfect design. Then you can do it all again. Try different motor arrangements, add your own LEGO bricks, experiment with different shapes—this kit is a wannabe engineer’s dream.

For the more advanced STEM learners out there, Flybrix lets you experiment with coding and block-based coding. It uses an arduino-based hackable circuit board, and the Flybrix app has advanced features that let you try your hand at software design.

Who is the Flybrix LEGO Drone Kit for?

Flybrix is a really fun way to introduce a number of core STEM concepts, which makes it ideal for kids—and technically, that’s who it was designed for. But because engineering and coding can get a little complicated, the recommended age for independent experimentation is 13 and up. However, kids younger than 13 can certainly work on Flybrix drones with the help of their parents. In fact, it actually makes a fantastic family hobby.

The constant stream of information about the novel coronavirus and COVID-19 can cause a lot of anxiety. Mental Floss created this semiweekly digest so you can peruse the news at your own pace—without feeling overwhelmed.

June 2, 2020

Researchers around the world are still trying to figure out what makes the new coronavirus so contagious and so lethal. Early on, physicians thought the virus was primarily a respiratory virus affecting the lungs. But with other symptoms beginning to emerge—blood clots, “Covid toes,” and a syndrome in children resembling Kawasaki disease—some researchers are beginning to think that COVID-19 is a disease of the blood vessels instead. Medium explains.

If you’ve had COVID-19 and present antibodies, does that mean you’re immune from another infection? How long does immunity last? What is immunity, exactly? Katherine J. Wu, who has a Ph.D. in microbiology and immunobiology from Harvard, breaks down the complicated ways our immune system protects us from pathogens.

Pharmaceutical company Eli Lilly has started the first human trial of a COVID-19 treatment based on antibodies. According to CNN, the Phase 1 trial will test the safety of a lab-engineered monoclonal antibody therapy that was based on antibodies sampled from COVID-19 survivors. Results of the randomized, double-blind, placebo-controlled trial will be known later this month.

Finally, Dr. Anthony Fauci talks with STAT's Helen Branswell about the state of “warp speed” coronavirus vaccine research and other hot topics in a characteristically forthright interview.

Japan declared a national emergency in early April to combat the spread of coronavirus. Now, a few days before the order was set to expire, Prime Minister Shinzo Abe is lifting the state of emergency in all but eight of Japan’s 47 prefectures. See how public health efforts to root out “clusters” of COVID-19 contained the disease in this Science article.

Many Americans are still waiting to receive their stimulus payments from the government, and a few who have received the stimulus funds have mistaken the letters for scams or junk mail. The Washington Post describes the anonymous envelopes and debit cards linked to the “Money Network Cardholder Services of Omaha, Nebraska” arriving in mailboxes with little indication they’re actually from the U.S. Treasury. The IRS has posted a FAQ with info about the stimulus payment debit cards, and if you’ve received one, here are some answers about activating and using it.

Businesses and offices around the world are beginning to reopen, which necessitates creative solutions for maintaining social distancing among employees and customers. The CDC has just issued guidelines for redesigning office spaces in the pandemic, some of which seem doable (such as adding clear dividers between closely-spaced desks) and some that seem well-nigh impossible (keeping people six feet apart in elevators and getting rid of communal coffee makers). And in France, a designer has come up with a similar tool for restaurant patrons: these giant Plexiglass “lampshades” that shield wearers from other people’s droplets.

Finally, it’s Friday, and most of us are still stuck at home. Now would be a great time to adopt the Swedish tradition of Fredagsmys, loosely translated as “Taco Friday.” Swedes gather together on Friday nights to eat tacos and watch movies with their families, and really, is that so different from what we may already be doing? Here are a few recommendations for awesome heist flicks to start your own Taco Friday.

Coronavirus travel restrictions have trapped a Bolivian orchestra at a German palace since mid-March, CNN reports. When the Orquesta Experimental de Instrumentos Nativos left South America, Bolivia had registered no cases of COVID-19 and Germany was still accepting international flights. But days after their arrival, the musicians failed to get on one of the last flights out of Germany before Bolivia closed its borders. Since then, they’ve been staying in the guesthouse at Rheinsberg Palace, a rococo-style castle surrounded by picturesque grounds in northeastern Germany. We can think of worse places to be quarantined.

More cities and states are allowing certain business to reopen during the continuing coronavirus pandemic. The New York Times has a frequently updated, state-by-state guide to the new rules.

Just FYI, rats are becoming more aggressive in their search for food. The Washington Post reports that the urban rodents are having a hard time with bars and restaurants closed, since they’re not producing the garbage and food scraps the rats would normally feast upon. In extreme cases, rats are even turning to cannibalism. Here are the CDC’s new guidelines for keeping them away from your trash cans.

Speaking of nature, a new article in Scientific American looks into how the environment will record the coronavirus pandemic. In a recent example, scientists examining Alpine ice cores discovered that the amount of lead pollution in the atmosphere decreased suddenly only once in 2000 years: between 1349 and 1353, when the Black Death engulfed Europe. In the future, tree rings and ice cores might show a remarkable decrease in greenhouse gas emissions in early 2020.

In two new studies published in the journal Science, researchers at Boston’s Beth Israel Deaconness Medical Center report promising results in battling the new coronavirus. For the first experiment, nine rhesus macaques were exposed to the new coronavirus and came down with COVID-19. After they recovered, researchers again exposed them to the virus, and the monkeys did not get sick—suggesting that they developed antibodies that protected them from reinfection. In the second study, researchers gave six experimental vaccines to 25 monkeys, then exposed those animals and 10 control monkeys to the virus. The vaccinated subjects showed “a substantial degree of protection,” one of the researchers told Reuters. Larger studies and human subjects will be the likely next step.

“Oh sh*t,” tweeted one virologist when she saw this study confirming the presence of infectious coronavirus particles in human poop. It gets worse: The study authors suggest that more research into “fecal-oral or fecal-respiratory transmission” of the coronavirus is warranted. And in a possibly related development, fatbergs may present another problem for treating coronavirus-contaminated sewage.

Memorial Day Weekend is here, though it still seems like mid-March because time and space are meaningless now. If you happen to be planning a summer road trip for 2020, follow these tips from The Washington Post, which suggest that vacations will be masked and sanitized for the foreseeable future. Here are a few more ideas.

Finally, if your summer vacation is going to be spent at home, check out these goods for a fun backyard movie night.

Remember the plight of the USS Theodore Roosevelt, the naval aircraft carrier whose captain pleaded with authorities to rescue his coronavirus-infected crew? (And then the captain was fired, and then the guy who fired him was fired, and then the captain was rehired in a different role?) It’s finally leaving port and heading back out to sea.

Speaking of aircraft, are planes safer than a car for travel these days? Medium talks to experts and finds that it really comes down to how tightly the vehicle is packed with non-related people.

And now that airlines and many other entities are requiring people to wear masks in public, you’ll need these tips for properly laundering your fabric face coverings.

Finally, a potential coronavirus vaccine from the pharmaceutical company Moderna has shown some positive results in a preliminary test. The Phase 1 trial in eight volunteers showed the vaccine at low doses was safe for use, but did not gauge its effectiveness or final dosage. The New York Times reports that the participants had a strong immune reaction to the vaccine and produced antibodies. Much larger Phase 2 and 3 trials scheduled to begin the summer will evaluate the vaccine’s efficacy.

A French dairy trade group is urging cheese lovers in France to fromagissons—basically, “let us act for cheese!”—to help farmers during the coronavirus pandemic. Citizens can do their part by scarfing down cheese from the regions of Saint-Nectaire, Reblochon, Cantal, and Camembert that would otherwise go to waste. BRB, moving to France …

Quarantine fatigue is sweeping the nation. Inverse talks to three experts about what this special type of fatigue looks like and offers some options for getting through it.

One way to battle quar exhaustion that seems to be working for us: Looking at these adorable baby animals born during the pandemic. CNN has the scoop on a newborn zebra at Disney’s Animal Kingdom theme park in Florida, two blue penguin chicks at the Bronx Zoo, and baby bison at Custer State Park in South Dakota. Personally, I’m in love with Sami the porcupette and her mom, Samantha, who were rescued by workers at Newhouse Wildlife Rescue in April.

Apparently, a segment of the male population is not OK with wearing face masks, despite numerous cities and states mandating masks in public to slow the spread of COVID-19 and statistics showing men are more susceptible to the disease. According to a non-peer-reviewed paper on PsyArXiv, men more than women were likely to view wearing a mask as “shameful, not cool, a sign of weakness, and a stigma.” You know what’s also a sign of weakness? Not being able to breathe because your lungs are filled with fluid!

And one more cautionary tale to take you into the weekend: a woman in Italy found out the hard way that drinking hand sanitizer does not protect you from coronavirus infection. The unnamed woman sipped two teaspoons of alcohol-based sanitizer every day for more than three weeks, then had to go to the emergency room for extreme abdominal pain. Doctors found “corrosive injury” to her digestive system. A better idea: wash your hands.

A new, free online course from Johns Hopkins University teaches the basics of contact tracing—which involves interviewing COVID-19 patients and determining whom they’ve been around. It’s one of the most important tools for stopping the spread of the new coronavirus. Once they’ve earned their certificate of course completion, students will be primed to apply for one of the thousands of contact tracer jobs in U.S. cities. The Washington Post reports that up to 100,000 contact tracers will be required to fight the pandemic, with as many as 10,000 needed in New York City (and there, the gig pays $57,000 a year [PDF]).  

If you live in New York, Maryland, or another state that has required people to wear face coverings in public, perhaps you’ve noticed the extreme variety in mask styles—from surgical masks to bandanas to homemade masks to hazmat respirators. NBC has some tips for choosing and buying a face mask, but the main thing to remember is that they won’t keep you completely safe from the new coronavirus. You still have wash your hands and practice social distancing if you need to leave home.

Healthcare workers hold orchids outside of a hospital
Maksim Axelrod, The Sill

Last week, houseplant boutique The Sill teamed up with Frontline Strong Relief and the orchid brand Just Add Ice to donate 10,000 orchids to healthcare workers in New York City’s Mount Sinai Hospital Network. Noting the mood-boosting power of plants, The Sill founder and CEO Eliza Blank said the gift is their way of thanking the city’s essential workers as well as celebrating Mother’s Day in the midst of a global crisis.

Certain segments of the internet have been swooning over Dr. Anthony Fauci’s no-nonsense handling of the coronavirus crisis, but a steamy 1991 romance novel called Happy Endings was there first. Famed D.C. hostess and author Sally Quinn based her handsome NIH scientist who has an affair with the widowed first lady on Fauci, just as Fauci was at the NIH developing treatments for AIDS. Washingtonian has the details.

The FDA gave emergency-use approval to a new CRISPR-based test that can diagnose COVID-19 in one hour, much faster than the six to eight hours of some current tests, Emily Mullin reports in Medium. CRISPR is a gene-editing technology that uses a molecular “guide” to find and target DNA and remove it from its sequence. In the new test, developed by Sherlock Biosciences, the molecular guide is sent to find the novel coronavirus’s genetic signature in a nose or throat swab. If it locates the signature, the guide releases a signal indicating a positive result. Its developers say the test can be run using standard lab equipment. 

Last week, several news outlets reported some younger COVID-19 patients developing serious blood clots or even having strokes while being otherwise healthy. It turns out that blood clots may not be such an unusual symptom of infectious disease, Roxanne Khamsi writes in WIRED. As far back as 1903, physicians noted the presence of clogged blood vessels in people with typhoid fever or bacterial diseases. So why is it so surprising now in COVID-19 patients? “It may be on account of our success at treating such [bacterial] infections,” Khamsi says.   

The military is temporarily banning recruits who have been hospitalized with COVID-19 from joining any of the armed forces, according to a Pentagon memo reported by The New York Times. Military officials may reconsider the guidance in the future, once more facts are known about the virus’s long-term effects in patients.

Let’s end on a positive note, shall we? The World Naked Bike Ride will go on, despite the pandemic—at least in Portland, Oregon. While other cities have canceled the event, Portland’s organizers are encouraging nude cyclists to participate on June 27 while maintaining proper social distancing.

With so many families unable to visit loved ones in hospitals and nursing homes, some folks are getting creative with their means of connection. When his mother couldn’t visit her 95-year-old father in a Toronto hospital, Avi Minkowitz asked his friend to drive his cherry-picker truck to the facility. His mom got into the bucket and was hoisted up three stories so she could see her beloved dad outside his third-floor window. Read more in this heartwarming essay.

New York City officials began distributing 7.5 million free masks to residents last weekend after the mayor said hospitals and health care workers were adequately supplied with PPE. People can pick up the masks in parks, schools, and food distribution centers (check here for a map of giveaway points in parks). All New Yorkers are required to wear a face covering in public, especially in scenarios where social distancing is difficult.

Tracy Wilk wanted to help out on the front lines of the coronavirus pandemic, but she’s a chef, not a doctor. So she launched a campaign, Bake It Forward, while furloughed from her job as an instructor at the Institute of Culinary Education. Wilk creates batches of delicious cookies and gives them to nurses, physicians, and hospital staff who need a little pick-me-up. “A lot of those health care workers have been working overtime. I’ve done those days before in the kitchen,” Wilk told Good Morning America. “A cookie isn’t going to change it, but it’s going to help workers on the front lines, and those little bits of joy are what makes the day better.”

As we learn more about the novel coronavirus, “COVID toes” is emerging as a possible new symptom. Some people have exhibited reddish lesions on their toes and then tested positive for COVID-19 without showing the typical signs of infection, such as a fever or dry cough. According to the Cleveland Clinic, those with “COVID toes” or unexplained rashes should contact their doctor and seek a coronavirus test.

People quarantining at home are feeding their sweet tooths (or is it teeth?). Sales of Kellogg’s breakfast cereals, which include Special K, Frosted Mini-Wheats, Pop Tarts Cereal, and many more, increased 3 percent in its latest earnings report thanks to the pandemic, the company said. Frozen food sales jumped 9 percent.

Stressed-out, home-bound parents are turning to Zoom babysitters when they need a break from working, teaching, and childcare. One sitter told The Washington Post that the most difficult part of the job was getting kids back in front of the screen when they wander off.

An NIH study of more than 1000 COVID-19 patients showed that the antiviral drug remdesivir reduced hospital stays to average of 11 days compared to 15 days for patients who received a placebo. The death rate was not reduced significantly. While the results of the study were modest, Dr. Anthony Fauci told reporters that “it is a very important proof of concept, because what it has proven is that a drug can block this virus.”

Could drive-in movie theaters make a comeback? With traditional cinemas closed across the country, drive-ins offer the thrill of a summer blockbuster in the sanitized safety of your vehicle, with a dash of mid-century nostalgia thrown in. About 300 still exist, including the Family Drive-In Theatre near Winchester, Virginia, which has recently sold out its weekend shows of Sonic the Hedgehog.

The CDC added six symptoms to its list of common signs of possible COVID-19 infection. Along with fever, cough, and shortness of breath, the new list includes chills, repeated shaking with chills, muscle pain, headache, sore throat, and loss of smell or taste. NPR reports that the expanded list of symptoms might allow more people to qualify for coronavirus testing, since people generally need to show signs of infection to be tested. One scary potential symptom is not yet included: blood clots that are leading to strokes in younger, otherwise mildly symptomatic COVID-19 patients. The Washington Post has that story.

Preliminary results from an Oxford University-based effort to develop a vaccine against the new coronavirus are promising, The New York Times reveals. Six rhesus macaque monkeys were given an experimental vaccine, exposed to copious amounts of the virus, and remained healthy. Human trials are next.

N95 masks have been in short supply since the pandemic began, so a group of Boston-based researchers set about finding a simple way to decontaminate masks for reuse. In a not-yet-peer-reviewed paper appearing on the preprint server medRxiv, they suggest that steaming a mask in the microwave over a dish of hydrogen peroxide effectively removed viral particles. While the method hasn’t been tested on a large scale, it could present a way for individual healthcare workers to reuse previously worn masks.

Doctors and nurses have self-isolated in RVs and hotel rooms to avoid bringing the new coronavirus into their own families. But one doctor in Texas may be having a slightly more fun time that most in quarantine: He’s camping out in his sons’ treehouse, conveniently located within shouting distance of his actual home. ER doctor Jason Barnes told the Corpus Christie Caller Times that his wife cooks meals for him and leaves them on a table outside, where he “[grabs] it before the dogs can get it.” 

You might be wearing your mask wrong. If your mask only covers your mouth or hangs around your neck while you talk on the phone, you’re not using it properly. The Huffington Post has some tips to get the most out of your cloth face covering—and also offers hints about the best fabrics for making your own. And, NPR reports on a not-yet-peer-reviewed study that suggests wearing a nylon stocking over your cloth mask keeps the mask tighter on your face and more effective at restraining your spittle.

Walmart and grocery stores are putting one-way traffic signs in their aisles to help shoppers move in a single direction throughout the stores, which is meant to encourage social distancing. At least two Mental Floss editors have recently witnessed very little adherence to the rules, though. Maybe the stores need to hire crossing guards.

A study highlighted last week in this digest found that cats were more susceptible to the virus than other mammals and birds. Now, the USDA is reporting that two pet kitties in different areas of New York State have tested positive for the coronavirus after visiting their vets with respiratory symptoms. There is still no evidence that people can contract COVID-19 from their pets. Fortunately, the two cats are expected to make a full recovery.

A 99-year-old World War II veteran in Britain vowed to raise money for the UK’s National Health Service (NHS) by walking 100 laps around his garden. On April 16, Captain Tom Moore completed his mission and raised a whopping £13 million ($16 million) for the public health service. Moore had started out on April 8 with a goal to raise £1000—but when supporters donated £70,000 in the first 24 hours, he upped his objective to £1 million. As The Guardian reports, Moore completed the last 25 laps on live television accompanied by a guard of honor from the 1st Battalion of the Yorkshire Regiment, Moore’s own regiment in the war. Now, his supporters are asking Queen Elizabeth II to give him a special commendation. And he turns 100 on April 30!

Similarly, 82-year-old Ontarian Annette Muller implored her daughter to run to the store with a sign in her window reading “need more wine.”

The coronavirus pandemic has hit the U.S. economy hard, but some small business owners are devising creative ways to help their staff. The owner of a Tybee Island, Georgia, bar spent three days un-stapling dollar bills—totaling more than $3000—from the walls and ceiling to give to her workers.

The Great Toilet Paper Shortage continues, but apparently some people are finding it at Walmart. The company’s CEO, Doug McMillon, told NBC’s Savannah Guthrie on April 10 that Walmart consumers bought enough toilet paper in five days to give every American a roll. (That’s about 328 million rolls, or 328 billion individual squares if every roll had 1000 sheets.)

Cats can catch coronavirus. A Chinese study in the journal Science found that the novel coronavirus replicates easily in cats and ferrets (which often stand in for humans in respiratory studies), but not as well in dogs, pigs, chickens, or ducks. More research is needed, though.

Almost 24 million people watched Queen Elizabeth II deliver a personal televised message about the coronavirus pandemic on Sunday, April 5. The queen thanked healthcare workers and those staying at home for their continued efforts in battling the outbreak, and said this address reminded her of her very first TV broadcast in 1940, when she offered a message to children who had been sent overseas for their own safety at the beginning of World War II. "We should take comfort that while we may have more still to endure, better days will return," the queen said. "We will be with our friends again. We will be with our families again. We will meet again." The queen rarely gives televised speeches apart from her annual Christmas message—this broadcast was only her fifth in her 68-year reign.

A tiger at the Bronx Zoo in New York City tested positive for COVID-19, the disease caused by the new coronavirus. The zoo's chief vet Paul Calle tweeted that Nadia, a 4-year-old Malayan tiger, had tests confirmed at the USDA's National Veterinary Services Laboratory after showing respiratory symptoms. Three other tigers exhibited the same symptoms, and zoo officials believe the big cats were exposed to the virus by an asymptomatic zoo employee. The Wildlife Conservation Society, which operates the Bronx Zoo, expects all the cats to fully recover. In a press release, the USDA said it's unlikely that your pet cat could transmit the virus to you, but if you feel sick, it's best to stay away from Fluffy as long as you have symptoms.

Should you be wearing a mask when you go outside? The answer is complicated, but New York City's mayor has begun urging residents to wear a fabric face covering to reduce the chance the virus could spread through breathing or talking.
