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.
