Most people know peanut butter as a staple from their childhood lunches or something that gets stuck to the roof of their mouth. But its applications extend far beyond the lunchbox. From making repairs around the home to making precious gemstones, here are some surprising things you can do with the protein-packed spread.

1. MAKE A GLOW-IN-THE-DARK SCIENCE EXPERIMENT

If you ever need something to do during a power outage, try experimenting with a sealed jar of peanut butter and a laser pointer. The crushing and heating process used to make peanut butter produces phenols, organic compounds that absorb light. Exposing fresh peanut butter to the violet light of a laser pointer will cause the phenols to glow green for a few seconds at a time.

2. GET YOUR MORNING CAFFEINE FIX

Peanut butter doesn't normally contain caffeine, but a serving of STEEM peanut butter packs more than a cup of coffee. Because it takes our bodies longer to absorb peanut butter than liquid coffee, the company claims that the caffeinated version of the treat offers a longer lasting energy boost than straight java—and will do it without any of the jittery side effects.

3. TURN IT INTO DIAMONDS

Peanut butter isn't considered a high-end product, but subject it to the extreme conditions of the Earth's mantle and that could change. A researcher in Germany successfully made a synthetic diamond using peanut butter as his source of carbon. The substance had to be squeezed with pressure 1.3 million times that of our atmosphere before a diamond was formed. But don't expect the peanut butter diamonds to be studding engagement rings anytime soon: The results were puny and impure compared to what's sold in jewelry stores.

4. REMOVE GUM

Maybe you fell asleep with gum in your mouth, or you blew a bubble that was just too big for your own good. Whatever the reason, odds are that you've gotten gum stuck in your hair at one point or another. In such cases, peanut butter has prevented many unwanted trips to the hairdresser. The oils in the product make gum less pliable and sticky, therefore easier to massage out of hair. The quick fix also works to free gum from other surfaces like clothing.

5. TREAT HICCUPS

Peanut butter is one of the lesser-known purported hiccup cures, but some people swear by it. The idea is that slowly consuming something thick and gooey like peanut butter will break up your swallowing and breathing patterns and dispel the hiccups. It also sounds way more enjoyable than holding your breath or standing on your head.

6. FEED ASTRONAUTS

Dining options are limited on the International Space Station, but even in space peanut butter sandwiches make an appearance on the menu. Assembling the meal up there isn't as easy as laying out the components on your kitchen counter. Instead of a jar, the peanut butter astronauts eat is stored in a flat-packed squeeze tube.

7. MAKE BAIT FOR FISH

Forget fancy lures: According to some experienced fishermen, peanut butter sandwiches make some of the best bait for catching codfish, catfish, carp, and bluegill. Prepare it on stale bread and garnish it with birdseed or garlic to make it especially irresistible.

8. REPAIR SCRATCHES

Depending on how long you’ve been holding on to it, your favorite CD or DVD likely has a scratch or two. But there's no reason to retire your scuffed-up discs for good: All you need is some peanut butter to extend the lifespan of your collection. Lightly rub the damaged surface with the peanut butter, set it down for a short while, and then remove the excess with a cloth. The scratches will still be there, but the oils from the peanuts will temporarily fill them in and smooth them out. You can also try the trick with your scratched-up wood furniture.

9. GET A HORSE TO "TALK"

Before the age of CGI, the makers of the sitcom Mister Ed used a much simpler method to get their equine star to "talk." The producers claimed that when they put peanut butter in the horse's mouth, he would move his lips to try to get it out. They dubbed the dialogue over this footage to create the illusion of a talking horse. (Though according to one theory, a wire attached to the horse's head was the primary source of the special effect.)

10. USE IT AS SHAVING CREAM

If you're open to mixing up your grooming routine, consider swapping your shaving gel with peanut butter. It's cheaper, works just as well, and, as a bonus, nourishes your skin with natural oils. Give it a shot if you don't mind smelling nutty and delicious for the rest of the day.

11. ESCAPE FROM PRISON

A group of prisoners at the Walker County Jail in Alabama were able to escape confinement using nothing but peanut butter and some clever deception. After smearing peanut butter on the numbers above their cell so it matched the number of the door leading outside, the inmates asked a new guard to let them into what they claimed to be their cell. From the control room, he inadvertently opened the front door and the escapees were able to walk right out. Despite the breakout, peanut butter sandwiches are still served at the prison.

12. REMOVE STICKERS

Peanut butter works the same magic on hard-to-peel stickers as it does on gum. Once you have your new purchase, peel off as much of the price sticker as possible and scrub away the stubborn residue with a dab of peanut butter. Peanut butter is also a great nontoxic way to remove stickers and glue from produce.

13. COOK SAVORY DISHES

It's no secret that peanut butter shines in sugary treats, whether in a cupcake or a candy bar. But peanut butter works just as well as a savory ingredient. If you have a jar in your pantry, you can add a dollop to punch up your instant ramen, or use it as a thickener in sauces or stews.

14. PREVENT DISEASE

You may already know that peanut butter is a great source of fiber and protein, but according to one study, the health benefits of eating the snack while you're young may extend to later in life. Researchers from the Washington University School of Medicine in St. Louis, Dana-Farber Cancer Institute, and Harvard Medical School found that women who consumed peanut butter on a regular basis between ages 9 and 15 decreased their chances of developing benign breast disease by age 30 by 39 percent.

15. BUILD A BIRD FEEDER

You may remember this one from summer camp—to build a cheap bird feeder at home, all you need is a pine cone, some peanut butter, bird seed, and string. Cover the pine cone in the peanut butter before rolling it in the seed to coat it. Use a string to hang it up from a nearby tree branch and watch the birds in your backyard gather to enjoy the homemade treat.

16. USE IT AS FROSTING

Looking for a more nutritious alternative to sugary frosting? Peanut butter makes the perfect topping for your baked goods. Spread it on chocolate cupcakes, cookies, or even doughnuts.

17. KEEP PETS OCCUPIED

If dogs love one thing more than playtime with their humans, it's peanut butter. The ingredient can be used to make a toy that your pet won't rip apart or get bored with after two minutes. Get your hands on a Kong or a similar hollow, rubber chew toy and fill it with a generous spoonful of peanut butter. While your dog spends the afternoon figuring out how to get it out, you can enjoy a few hours of peace and quiet.

18. MAKE EDIBLE SCULPTING DOUGH

Peanut butter is messier than real Play-Doh, but it's also a lot tastier. Mix half a cup of it with one cup of powdered sugar and two tablespoons of honey to get a material that's the perfect consistency for rolling, shaping, and squeezing. And once your creations are complete, they can make a wholesome post-playtime bite.

19. MAKE MEDICINE MORE APPEALING

This trick is a favorite with parents of pets and kids. Before giving a pill to a dog, cat, or young child, hide it in a gob of peanut butter. The medication they turned their noses up at moments ago suddenly becomes a lot easier to swallow.

20. GET A POST-WORKOUT PROTEIN BOOST

Fueling up right after exercising is essential to replenishing your energy stores and repairing and building up muscles. Peanut butter is one of the best foods you can include in your post-workout snack. The carbs, fats, and proteins in a serving are exactly what your body needs after being pushed to the limit.

21. QUALITY TEST PRODUCTS

The world's most perfect jar of peanut butter is produced by the federal government. At a price of $220 for a 6-ounce jar, the National Institute of Standards and Technology sells the flawless spread to food manufacturers developing their own peanut-based products. By testing "Standard Reference Material No. 2387" in the lab, they can see how the vitamin, mineral, and aflatoxin levels in their own peanut butters stack up.

22. BUILD A 444-POUND PEANUT BUTTER CUP

In 2015, a Los Angeles-area candy shop lined a plastic kiddie pool with melted chocolate and filled it with peanut butter in an attempt to break the world record for largest peanut butter cup. The monstrous confection ended up weighing 444 pounds. Afterwards, it was broken up into smaller pieces and sold to raise money for charity.

23. USE IT AS CONDITIONER

You don't have to wait to get gum stuck in your hair to lather it up with peanut butter. The oils and nutrients it contains make it a great natural alternative to leave-in conditioner. Just work it into your hair, allow it to sit for a while, and wash it out to find vibrant, lustrous locks underneath.

24. MAKE A FACEMASK

The same properties that make peanut butter a nourishing hair treatment also make it a soothing face mask. A peanut butter facial works best on dry skin and shouldn't be applied to faces that are already oily.

25. SHINE LEATHER

Your dull leather is only a few dabs of peanut butter away from looking as good as new. Rub it into the material you want to shine by making tiny circles with your fingers, then use a towel or washcloth to wipe it off. The polishing hack also works on leather shoes.

19 Every Day Things Science Hasn’t Figured Out

Science has enabled humans to complete some pretty incredible feats, like land on the moon, for example. But when it comes to common things like laughter or hiccups, scientists still can’t quite figure out the reason behind them. In this article, which was adapted from The List Show on YouTube, we look at everyday things that are still a mystery.

1. It's still not understood why we cry.

Crying is still a scientific mystery. Physiologically, it’s clear what’s happening when someone cries. But, it has been more difficult to figure out the evolutionary reason for tears. We know that babies cry to communicate and get attention. So, some experts believe that adults might also cry for social reasons, like to bond or to warn others that something is amiss.

2. The reason we laugh is still unknown.

Like crying, we also don’t know why people evolved the ability to laugh, but experts guess it has something to do with communication—and not just that we find something funny. One researcher found that only 20 percent of laughs he looked at were preceded by anything deemed in any way humorous.

It's possible we laugh to let other people know that we’re okay or to bond with each other. A study published in 2016 gave evidence for the latter. Researchers found that an outside observer could distinguish whether laughter was produced between a pair of strangers or a pair of friends.

3. Scientists haven't figured out why we blush.

Blushing is often telling others things we don’t want them to know, like the fact that we’ve done something wrong or embarrassing. Some experts believe that we may have evolved blushing to show submission to group leaders. Others think it may have something to do with the fact that blushing people have been shown to be considered more likable, so it helps peers look past the bad things we’ve done.

4. It's still unclear why anesthesia makes us pass out.

General anesthesia has been in use in the United States since 1846, but there are still some uncertainties about why the chemicals in anesthetics cause people to pass out. A recent study showed that the drugs affect proteins in the brain and the reason we go unconscious has to do with altering neural activity, but more research is needed.

5. We aren't exactly sure what consciousness is.

Consciousness is frequently defined as how we feel present and alive in the world. But the question is: Why and how do we feel conscious? It’s of interest in both philosophy and science. Scientists would like to know which part of the brain is responsible for consciousness, but it’s still a mystery.

6. It's unclear exactly how medications like Tylenol work.

We don’t 100 percent understand how pain relievers containing acetaminophen give us pain relief. We do know that acetaminophens aren’t totally consistent; they’re more effective in some types of cells than in others. So for now, scientists believe the drugs might be a specific type of enzyme inhibitor.

7. We aren't sure why we get hiccups or how to stop them.

Scientists don’t know what causes hiccups, what purpose they serve, or how to cure them. A lot of people have favorite techniques, from gargling water to pulling hard on the tongue, but there’s no scientifically-proven way to get rid of them.

In 2002, one researcher tried to get to the bottom of the problem by looking at how 54 hospital patients had been treated for hiccups. They tried multiple treatments, like holding their breath and medication, but none were proven effective.

8. Scientists haven't figured out why tornadoes start.

We don’t know why only some thunderstorms create tornadoes and others don’t. Generally, it’s understood that tornadoes come to be when cold, dry air interacts with warm, humid air. But the thunderstorms that result from those air conditions only sometimes cause tornadoes.

9. Scientists also haven't figured out why tornadoes end.

It’s also unclear why tornadoes die—though experts believe that at least sometimes it has to do with the tornado’s interaction with cold temperatures.

10. It's still uncertain why we need to sleep.

There are theories as to why we need sleep, but no one knows for sure. It's possible our ancestors slept because it kept them out of danger during the night. Or it could be an energy conserving function. What we do know is that sleep helps us recover from the day, and there’s evidence it changes the connections in our brains.

11. The reason we dream is still unclear.

Similarly, there are no clear answers as to why we dream. Some sleep experts think dreaming doesn’t have a purpose at all. Others have theories, like that we’re playing out threatening situations, like being chased, so that we’re better equipped to handle danger while awake.

12. We still aren't sure why we have the urge to scratch.

We often understand why we itch. But, we don’t completely understand why we have the urge to scratch. The body has receptors just for itches that are almost identical to those that convey pain, and it’s thought that scratching might interfere with these signals. But at the same time, it might cause the skin to get more irritated, which causes even more itching.

13. Science still hasn't figured out the cure for aging.

Scientists know some things about why we age, but no one has fully figured it out. There’s little evidence for popular hypotheses having to do with things like free radicals and telomeres. Aging is probably the result of a complex group of poorly understood processes, meaning a cure isn’t happening any time soon.

14. Ornithologists still don't know why only some birds migrate.

It’s also unclear why some birds migrate while others don’t. The ones that do migrate might do it to conserve energy, which might be kind of confusing, since they’re flying great distances and therefore expending a lot of energy to get to their destination. But it’s likely worth it since they’re probably traveling somewhere with abundant energy sources—a.k.a., plenty of available food. Luckily, thanks to technology like tracking devices, scientists are able to track birds more easily and are now learning much more about migration.

15. Scientists haven't figured out the “nature vs. nurture” debate.

The question of nature versus nurture hasn’t been settled yet. Technically, we know that our genes interact with our environment to foster characteristics—but science isn’t sure to what extent. A complicating factor is that it varies by trait and individual person. How much your genes are influencing your IQ, for instance, may be different from someone else.

16. We still aren't sure why the placebo effect happens.

The placebo effect is pretty mysterious. It has been proven again and again that sugar pills and other fake treatments can actually make someone feel better. And it’s not just a feeling as scans have shown that placebos affect the area of the brain associated with pain. We still don’t know why. It’s believed that placebos somehow help release endorphins, but experts need more information.

17. It's still unclear why bicycles are able to stay up on their own.

Have you ever given a bike with no one on it a push and noticed that it stays up on its own? It doesn’t fall over for much longer than you expect, and we don’t know how it manages to balance itself while moving.

18. How skates work on ice is still unknown.

And another mystery of physics: How do skates work on ice? There is a popular theory. We know that ice has a very thin layer of liquid on it. So, a skate moving quickly on top of ice might make more liquid because the friction causes melting. The skate is actually changing the ice itself, creating a path on which to glide.

19. There still isn't a cure for the common cold.

We get colds from seven separate families of viruses and those families have sub-viruses. So, to cure the “cold,” there would need to be a cure that acts as a catch-all for about 200 sub-viruses.

6 Surprising Facts About Nintendo's Animal Crossing

Nintendo
Nintendo

by Ryan Lambie

Casting you as a newcomer in a woodland town populated by garrulous and sometimes eccentric creatures, Nintendo’s Animal Crossing is about conversation, friendship, and collecting things rather than competition or shooting enemies. It’s a formula that has grown over successive generations—which is all the more impressive, given the game’s obscure origins. The 3DS version now one of the most popular games available for that system, and the franchise was catapulted into further fame when Animal Crossing: New Horizons was released on Nintendo Switch in March 2020. Here are a few things you may not know about the video game.

1. Animal Crossing’s inspiration came from an unlikely place.

By the late 1990s, Katsuya Eguchi had already worked on some of Nintendo’s greatest games. He’d designed the levels for the classic Super Mario Bros 3. He was the director of Star Fox (or Star Wing, as it was known in the UK), and the designer behind the adorable Yoshi’s Story. But Animal Crossing was inspired by Eguchi’s experiences from his earlier days, when he was a 21-year-old graduate who’d taken the decisive step of moving from Chiba Prefecture, Japan, where he’d grown up and studied, to Nintendo’s headquarters in Kyoto.

Eguchi wanted to recreate the feeling of being alone in a new town, away from friends and family. “I wondered for a long time if there would be a way to recreate that feeling, and that was the impetus behind Animal Crossing,” Eguchi told Edge magazine in 2008. Receiving letters from your mother, getting a job (from the game’s resident raccoon capitalist, Tom Nook), and gradually filling your empty house with furniture and collectibles all sprang from Eguchi’s memories of first moving to Kyoto.

2. Animal Crossing was originally developed for the N64.

Although Animal Crossing would eventually become best known as a GameCube title—to the point where many assume this is where the series began—the game actually originally appeared on the N64. First developed for the ill-fated 64DD add-on, Animal Crossing (or Dōbutsu no Mori, which translates to Animal Forest) was ultimately released as a standard cartridge. But by the time Animal Crossing emerged in Japan in 2001, the N64 was already nearing the end of its lifespan, and it was never localized for a worldwide release.

3. Translating Animal Crossing for an international audience was a difficult task.

The GameCube version of Animal Crossing was released in Japan in December 2001, about eight months after the N64 edition. Thanks to the added capacity of the console’s discs, this version of the game included characters like Tortimer or Blathers that weren’t in the N64 iteration, and Animal Crossing soon became a hit with Japanese critics and players alike.

Porting Animal Crossing for an international audience proved to be a considerable task, however, with the game’s reams of dialogue and cultural references all requiring careful translation. But the effort writers Nate Bihldorff and Rich Amtower put into the English-language version would soon pay off; Nintendo’s bosses in Japan were so impressed with the additional festivals and sheer personality present in the western version of Animal Crossing, they decided to have that version of the game translated back into Japanese. This new version of the game, called Dōbutsu no Mori e+, was released in 2003.

4. K.K. Slider is based on Animal Crossing’s composer.

One of Animal Crossing’s most recognizable and popular characters is K.K. Slider, the laidback canine musician. He’s said to be based, both in looks and name, on Kazumi Totaka, the prolific composer and voice actor who co-wrote Animal Crossing’s music. In the Japanese version of Animal Crossing, K.K. Slider is called Totakeke—a play on the real musician’s name. K.K. Slider’s almost as prolific as Totaka, too: Animal Crossing: New Leaf on the Nintendo 3DS contains a total of 91 tracks performed by the character.

5. One Animal Crossing character has been known to make players cry.

A more controversial character than K.K. Slider, Mr. Resetti is an angry mole created to remind players to save the game before switching off their console. And the more often players forget to save their game, the angrier Mr. Resetti gets. Mr. Resetti’s anger apparently disturbed some younger players, though, as Animal Crossing: New Leaf’s project leader Aya Kyogoku revealed in an interview with Nintendo's former president, the late Satoru Iwata.

“We really weren't sure about Mr. Resetti, as he really divides people," Kyogoku said. “Some people love him, of course, but there are others who don't like being shouted at in his rough accent.” Iwata agreed, saying, “It seems like younger female players, in particular, are scared. I've heard that some of them have even cried.”

To avoid the tears, Mr. Resetti plays a less prominent role in Animal Crossing: New Leaf, and only appears if the player first builds a Reset Surveillance Centre. Divisive though he is, Mr. Resetti was designed and written with as much care as any of the other characters in Animal Crossing; his first name’s Sonny, he has a brother called Don and a cousin called Vinnie, and he prefers his coffee black with no sugar.

6. Animal Crossing is still evolving.

A game once inspired by the loneliness of moving to a new town has now become one of Nintendo’s most successful and beloved franchises. Since its first appearance in 2001, the quirky and disarming Animal Crossing has grown to encompass toys, a movie, and five main games (or six if you count the version released for the N64 as a separate entry). All told, the Animal Crossing games have sold more than 30 million copies, and the series is still growing. In late 2017, the mobile title Animal Crossing: Pocket Camp was released for iOS and Android—it was a big step for the franchise, as Nintendo is famously selective about which of its series get a mobile makeover. And in March 2020, Animal Crossing: New Horizon was released on Switch, selling a whopping 1.88 million physical copies during its first three days on the market.
