Annoy your kids with your newfound school supplies knowledge and they'll actually want to go back to school.

1. The Lunch Box

In the early part of the 20th century, most kids packed their school lunch in an empty cookie, biscuit, or tobacco tin. In 1935, a company called Aladdin tried to create a market for specialized lunch boxes by putting Mickey Mouse on the cover of their tin box. But even The Mouse couldn't convince kids to buy en masse. Aladdin didn't give up, though, and they had their first bonafide lunchtime hit in 1950 when they released the Hopalong Cassidy lunch box to young baby boomers. Available in red or blue, the box and thermos combination featured a crudely drawn picture of the popular TV and radio cowboy on one side.

As lackluster as that sounds, Aladdin sold 600,000 Hopalong lunch boxes in a single year. Hoping to hop in on Hopalong's success, the King of Cowboys, Roy Rogers, asked Aladdin about getting his own lunch box. But Aladdin turned him down, saying one cowboy was enough for them. So Rogers went to American Thermos, who upped the ante by covering the entire box and thermos with a full-color likeness of Rogers, setting a new standard in lunch box design. In 1953 alone, an impressive 2.5 million Roy Rogers lunch boxes were sold. But Roy's lunchtime reign was short-lived, because you can't keep a good mouse down. The Disney School Bus, featuring Mickey and the gang, became the most popular lunch box ever with 9 million units sold after it was released in 1956.

During the lunch box heyday, between 1950 and 1970, around 120 million boxes were sold, featuring cartoon characters, comic book heroes, Barbie, and even The Beatles. But things began to change when concerned moms started crusading against metal boxes, claiming they could be used as weapons on the schoolyard. Thanks to these efforts, the State of Florida banned metal lunch boxes in 1972, forcing the manufacturers to switch to plastic. After the change, sales declined quickly until 1985 when a metal Rambo lunch box for kids became the last of its kind. Today, soft, fabric lunch boxes are all the rage, but they still feature popular characters like Spider-Man, Batman, and, of course, Mickey Mouse.

2. Crayola Crayons

Early childhood education started in Europe in the 1820s, but didn't really take a foothold in America until the 1860s and '70s, when kindergartens began springing up all over the country. Even back then, art was considered an important part of a child's education; however most of the art supplies available at the time, like paint or pastels, were very messy in the hands of a five-year old. Wax crayons were recognized as a great solution to this problem, so as many as 300 companies began making them to cash in on the new, lucrative educational market.

However, there was one concern: most of the pigments used to make crayons were highly toxic. So when kids inevitably chewed on their drawing utensil, they wound up getting sick. That is until the Binney and Smith Company developed new, non-toxic pigments as part of their Crayola brand crayons, first released in 1903. The unforgettable name was created by Mrs. Binney when she combined the French word for chalk, craie, with the first part of the word oleaginous, meaning oily, which described the wax used to make the crayons. From their initial offering of eight colors, the line has expanded over the years to include 150 shades, including metallic versions and others with glitter infused into the wax.

And no discussion of crayons is complete without mentioning the classic Sesame Street tour of the Crayola Factory:

3. Elmer's Glue-All

For almost as long as kids have been eating glue, they've been eating Elmer's Glue-All. First released in 1947 by Borden, the dairy company, the glue wasn't a big seller until they added the now-familiar bull logo to the bottle. Over the years, rumors have spread that the bull meant the adhesive was made using animal hooves or hides, but those are just urban legends. In fact, the original Glue-All was made from casein, a milk by-product that Borden had in large supply thanks to their dairy operations.

The bull came to be on the label after Elsie, Borden's famous spokescow, was hired to star in the 1940 film Little Men. Her shooting schedule prevented her from attending the World's Fair that year where she had always been incredibly popular. So, in desperation, Borden found a bull they could use instead, called him Elmer, and said he was Elsie's husband. Elmer was a big hit with Fair-goers, too, so he became the spokesbull for the company's chemical division. His face was added to the glass bottle of Glue-All in 1951, which is when sales finally took off. A year later, the packaging changed to the now-familiar white plastic bottle with the orange dispenser tip and has stayed that way ever since.

4. The Mechanical Pencil

One of the drawbacks of the standard #2 pencil is that you have to sharpen it all the time. But with a mechanical pencil, all you do is click, click, click and you're good to go. It might surprise you to know that this mechanical marvel was first patented way back in 1822 by Sampson Mordan, who called it a "propelling pencil."

Concealed as a small cylinder, the pencil would expand in length as one end was pulled out, revealing the lead from the other side. When finished writing, the owner would simply collapse the pen into its original form, making the useful little device highly portable. They were especially popular with wealthy Victorians who preferred cylinders of silver or gold, the more ornately decorated the better, sometimes working precious stones into the end cap. Even laymen had propelling pencils, though, often cast in the likeness of animals, Egyptian mummies, cannons for the military man, or disguised as everyday items like nails and screws.

Mordan's design was just the start of a whole new industry, with nearly 200 mechanical pencil patents filed throughout the late 1800s, most featuring their own unique way of getting the lead out. The push-button, ratcheting design didn't come along until 1879, but it has stood the test of time and is now the most common type of mechanical pencil on the market.

5. Binder Clips

After your kids finish their first assignment of the school year, a 10-page paper titled, "What I Did Over Summer Vacation," they're going to have to bind all those pages together. Thankfully there are plenty of inventions available to do just that.

They could start with the most recent paper-holding innovation, the binder clip. Developed in 1910 by Louis E. Baltzley, the flexible black metal clip with silver handles has remained unchanged for over 100 years, proving the old adage, "If it ain't broken, don't fix it."

6. 3-Ring Binders

Another option would be a 3-ring binder, invented by German office supply innovator Friedrich Soennecken in 1886. Naturally, he invented the hole punch to go along with the binder, too. He also contributed to the style of penmanship known as "round writing," a predecessor to the cursive handwriting that we all spent hours and hours practicing in elementary school.

7. The Stapler

Of course there's always the stapler, which went through many variations until Henry Heyl patented his design in 1877. The key difference between Heyl's stapler and earlier models was the ability to not only punch the staple through the paper, but to also bend the staple prongs under once it was through, thus securing the pages together in one motion. But with Heyl's design, you still had to feed the staples in one at a time. A spring-loaded magazine was soon developed that could feed the staples into the rest of the mechanism.

When stationery wholesaler Jack Linksy founded the Parrot Speed Fastener Corporation in the 1930s, few could've imagined that his humble company—later known as Swingline—would change the world of paper-fastening forever. But that's just what he did when he developed the 1937 Swingline Speed Stapler No. 3. According to Linsky's son-in-law Alan Seff, to load a stapling machine before the Swingline came along, "you practically needed a screwdriver and a hammer to put the staples in. He and his engineers devised a patented unit where you just opened the top of the machine, and you'd plunk the staples in." Amazingly enough, the mechanics of the modern stapler have remained virtually unchanged.

8. The Paperclip

Last but not least is the granddaddy of paper binding technologies—the mighty paperclip. Since the late 1860s, there had been a handful of bent-wire clasp designs that used friction to hold papers together. But the curved clip we're all familiar with, known as the "Gem," was first introduced around 1892. No one ever took out an official patent for the design, so there's no definitive record of when it was actually developed.

Because of this hazy history, the invention has been attributed to many different people over the years, perhaps most famously to English sociologist and Charles Darwin-enthusiast Herbert Spencer, who coined the term "survival of the fittest." There's also a Norwegian, Johan Vaaler, who designed a series of clips that were successfully patented in 1901, though they were far from the first. However, because patriotic Norwegians wore paperclips on their lapels as a symbol of unity during the Nazi occupation of World War II, the legend of Vaaler's innovation grew as a matter of national pride. Unfortunately, none of his designs were put into production before his patent expired, so neither he, nor anyone else for that matter, can truly be called the inventor of the paperclip.

8 Tricks to Help Your Cat and Dog to Get Along

When people aren’t debating whether cats or dogs are more intelligent, they’re equating them as mortal foes. That’s a stereotype that both cat expert Jackson Galaxy, host of the Animal Planet show My Cat From Hell, and certified dog trainer Zoe Sandor want to break.

Typically, cats are aloof and easily startled, while dogs are gregarious and territorial. This doesn't mean, however, that they can't share the same space—they're just going to need your help. “If cats and dogs are brought up together in a positive, loving, encouraging environment, they’re going to be friends,” Galaxy tells Mental Floss. “Or at the very least, they’ll tolerate each other.”

The duo has teamed up in a new Animal Planet series, Cat Vs. Dog, which airs on Saturdays at 10 p.m. The show chronicles their efforts to help pet owners establish long-lasting peace—if not perfect harmony—among cats and dogs. (Yes, it’s possible.) Gleaned from both TV and off-camera experiences, here are eight tips Galaxy and Sandor say will help improve household relations between Fido and Fluffy.

1. TAKE PERSONALITY—NOT BREED—INTO ACCOUNT.

Contrary to popular belief, certain breeds of cats and dogs don't typically get along better than others. According to Galaxy and Sandor, it’s more important to take their personalities and energy levels into account. If a dog is aggressive and territorial, it won’t be a good fit in a household with a skittish cat. In contrast, an aging dog would hate sharing his space with a rambunctious kitten.

If two animals don’t end up being a personality match, have a backup plan, or consider setting up a household arrangement that keeps them separated for the long term. And if you’re adopting a pet, do your homework and ask its previous owners or shelter if it’s lived with other animals before, or gets along with them.

2. TRAIN YOUR DOG.

To set your dog up for success with cats, teach it to control its impulses, Sandor says. Does it leap across the kitchen when someone drops a cookie, or go on high alert when it sees a squeaky toy? If so, it probably won’t be great with cats right off the bat, since it will likely jump up whenever it spots a feline.

Hold off Fido's face time with Fluffy until the former is trained to stay put. And even then, keep a leash handy during the first several cat-dog meetings.

3. GIVE A CAT ITS OWN TERRITORY BEFORE IT MEETS A DOG.

Cats need a protected space—a “base camp” of sorts—that’s just theirs, Galaxy says. Make this refuge off-limits to the dog, but create safe spaces around the house, too. This way, the cat can confidently navigate shared territory without trouble from its canine sibling.

Since cats are natural climbers, Galaxy recommends taking advantage of your home’s vertical space. Buy tall cat trees, install shelves, or place a cat bed atop a bookcase. This allows your cat to observe the dog from a safe distance, or cross a room without touching the floor.

And while you’re at it, keep dogs away from the litter box. Cats should feel safe while doing their business, plus dogs sometimes (ew) like to snack on cat feces, a bad habit that can cause your pooch to contract intestinal parasites. These worms can cause a slew of health problems, including vomiting, diarrhea, weight loss, and anemia.

Baby gates work in a pinch, but since some dogs are escape artists, prepare for worst-case scenarios by keeping the litter box uncovered and in an open space. That way, the cat won’t be cornered and trapped mid-squat.

4. EXERCISE YOUR DOG'S BODY AND MIND.

“People exercise their dogs probably 20 percent of what they should really be doing,” Sandor says. “It’s really important that their energy is released somewhere else so that they have the ability to slow down their brains and really control themselves when they’re around kitties.”

Dogs also need lots of stimulation. Receiving it in a controlled manner makes them less likely to satisfy it by, say, chasing a cat. For this, Sandor recommends toys, herding-type activities, lure coursing, and high-intensity trick training.

“Instead of just taking a walk, stop and do a sit five times on every block,” she says. “And do direction changes three times on every block, or speed changes two times. It’s about unleashing their herding instincts and prey drive in an appropriate way.”

If you don’t have time for any of these activities, Zoe recommends hiring a dog walker, or enrolling in doggy daycare.

5. LET CATS AND DOGS FOLLOW THEIR NOSES.

In Galaxy's new book, Total Cat Mojo, he says it’s a smart idea to let cats and dogs sniff each other’s bedding and toys before a face-to-face introduction. This way, they can satisfy their curiosity and avoid potential turf battles.

6. PLAN THE FIRST CAT/DOG MEETING CAREFULLY.

Just like humans, cats and dogs have just one good chance to make a great first impression. Luckily, they both love food, which might ultimately help them love each other.

Schedule the first cat-dog meeting during mealtime, but keep the dog on a leash and both animals on opposite sides of a closed door. They won’t see each other, but they will smell each other while chowing down on their respective foods. They’ll begin to associate this smell with food, thus “making it a good thing,” Galaxy says.

Do this every mealtime for several weeks, before slowly introducing visual simulation. Continue feeding the cat and dog separately, but on either side of a dog gate or screen, before finally removing it all together. By this point, “they’re eating side-by-side, pretty much ignoring each other,” Galaxy says. For safety’s sake, continue keeping the dog on a leash until you’re confident it’s safe to take it off (and even then, exercise caution).

7. KEEP THEIR FOOD AND TOYS SEPARATE.

After you've successfully ingratiated the cat and dog using feeding exercises, keep their food bowls separate. “A cat will walk up to the dog bowl—either while the dog’s eating, or in the vicinity—and try to eat out of it,” Galaxy says. “The dog just goes to town on them. You can’t assume that your dog isn’t food-protective or resource-protective.”

To prevent these disastrous mealtime encounters, schedule regular mealtimes for your pets (no free feeding!) and place the bowls in separate areas of the house, or the cat’s dish up on a table or another high spot.

Also, keep a close eye on the cat’s toys—competition over toys can also prompt fighting. “Dogs tend to get really into catnip,” Galaxy says. “My dog loves catnip a whole lot more than my cats do.”

8. CONSIDER RAISING A DOG AND CAT TOGETHER (IF YOU CAN).

Socializing these animals at a young age can be easier than introducing them as adults—pups are easily trainable “sponges” that soak up new information and situations, Sandor says. Plus, dogs are less confident and smaller at this stage in life, allowing the cat to “assume its rightful position at the top of the hierarchy,” she adds.

Remain watchful, though, to ensure everything goes smoothly—especially when the dog hits its rambunctious “teenage” stage before becoming a full-grown dog.

10 Juicy Facts About Sea Apples

They're both gorgeous and grotesque. Sea apples, a type of marine invertebrate, have dazzling purple, yellow, and blue color schemes streaking across their bodies. But some of their habits are rather R-rated. Here’s what you should know about these weird little creatures.

1. THEY’RE SEA CUCUMBERS.

The world’s oceans are home to more than 1200 species of sea cucumber. Like sand dollars and starfish, sea cucumbers are echinoderms: brainless, spineless marine animals with skin-covered shells and a complex network of internal hydraulics that enables them to get around. Sea cucumbers can thrive in a range of oceanic habitats, from Arctic depths to tropical reefs. They're a fascinating group with colorful popular names, like the “burnt hot dog sea cucumber” (Holothuria edulis) and the sea pig (Scotoplanes globosa), a scavenger that’s been described as a “living vacuum cleaner.”

2. THEY'RE NATIVE TO THE WESTERN PACIFIC OCEAN.

Sea apples have oval-shaped bodies and belong to the genus Pseudocolochirus and genus Paracacumaria. The animals are indigenous to the western Pacific, where they can be found shuffling across the ocean floor in shallow, coastal waters. Many different types are kept in captivity, but two species, Pseudocolochirus violaceus and Pseudocolochirus axiologus, have proven especially popular with aquarium hobbyists. Both species reside along the coastlines of Australia and Southeast Asia.

3. THEY EAT WITH MUCUS-COVERED TENTACLES.

Sea cucumbers, the ocean's sanitation crew, eat by swallowing plankton, algae, and sandy detritus at one end of their bodies and then expelling clean, fresh sand out their other end. Sea apples use a different technique. A ring of mucus-covered tentacles around a sea apple's mouth snares floating bits of food, popping each bit into its mouth one at a time. In the process, the tentacles are covered with a fresh coat of sticky mucus, and the whole cycle repeats.

4. THEY’RE ACTIVE AT NIGHT.

Sea apples' waving appendages can look delicious to predatory fish, so the echinoderms minimize the risk of attracting unwanted attention by doing most of their feeding at night. When those tentacles aren’t in use, they’re retracted into the body.

5. THE MOVE ON TUBULAR FEET.

The rows of yellow protuberances running along the sides of this specimen are its feet. They allow sea apples to latch onto rocks and other hard surfaces while feeding. And if one of these feet gets severed, it can grow back.

6. SOME FISH HANG OUT IN SEA APPLES' BUTTS.

Sea apples are poisonous, but a few marine freeloaders capitalize on this very quality. Some small fish have evolved to live inside the invertebrates' digestive tracts, mooching off the sea apples' meals and using their bodies for shelter. In a gross twist of evolution, fish gain entry through the back door, an orifice called the cloaca. In addition expelling waste, the cloaca absorbs fresh oxygen, meaning that sea apples/cucumbers essentially breathe through their anuses.

7. WHEN THREATENED, SEA APPLES CAN EXPAND.

Most full-grown adult sea apples are around 3 to 8 inches long, but they can make themselves look twice as big if they need to escape a threat. By pulling extra water into their bodies, some can grow to the size of a volleyball, according to Advanced Aquarist. After puffing up, they can float on the current and away from danger. Some aquarists might mistake the robust display as a sign of optimum health, but it's usually a reaction to stress.

8. THEY CAN EXPEL THEIR OWN GUTS.

Sea apples use their vibrant appearance to broadcast that they’re packing a dangerous toxin. But to really scare off predators, they puke up some of their own innards. When an attacker gets too close, sea apples can expel various organs through their orifices, and some simultaneously unleash a cloud of the poison holothurin. In an aquarium, the holothurin doesn’t disperse as widely as it would in the sea, and it's been known to wipe out entire fish tanks.

9. SEA APPLES LAY TOXIC EGGS.

These invertebrates reproduce sexually; females release eggs that are later fertilized by clouds of sperm emitted by the males. As many saltwater aquarium keepers know all too well, sea apple eggs are not suitable fish snacks—because they’re poisonous. Scientists have observed that, in Pseudocolochirus violaceus at least, the eggs develop into small, barrel-shaped larvae within two weeks of fertilization.

10. THEY'RE NOT EASILY CONFUSED WITH THIS TREE SPECIES.

Syzgium grande is a coastal tree native to Southeast Asia whose informal name is "sea apple." When fully grown, they can stand more than 140 feet tall. Once a year, it produces attractive clusters of fuzzy white flowers and round green fruits, perhaps prompting its comparison to an apple tree.
