We use countless objects daily without questioning their design, yet many have hidden features or were meant for entirely different purposes. From kitchen tools to bananas, here are 11 everyday items you might be using all wrong—or that at least have surprising secrets built in.

Yes, toothpaste was always intended to clean and polish teeth, but its mild abrasives make it effective for cleaning jewelry, removing stains from clothing, and even defogging mirrors.

Interestingly, the first toothpaste-like substance dates back to ancient Egypt, where a blend of pumice and vinegar was used for oral care. Modern toothpaste, which includes ingredients like baking soda—another household staple—explains why it’s so effective on surfaces beyond just teeth.

That hole in your pasta spoon isn’t just for draining water; it can also help measure a perfect portion of dry spaghetti!

A single serving of spaghetti is about the amount that fits through the hole. This design prevents cooking too much or too little, though not all pasta spoons have holes large enough for accurate measuring.

The latch inside gas pump nozzles was originally designed to shut off fuel flow automatically when the tank is full, not to hold the pump open.

Modern pumps use this mechanism as a safety feature, preventing spills and overflows. In some places, using the latch to hold the nozzle open is even illegal due to fire risks.

Those metal loops on the back of grocery cart seats aren’t just for show—they’re designed to hold plastic bags with fragile items.

Hanging lighter bags here prevents them from being crushed by heavier groceries in the cart, yet few shoppers take advantage of this simple design. So, next time you go shopping, give it a try—it could be a real lifesaver.

The hole in a soda can tab isn’t just part of the opening mechanism—it can double as a straw holder. Once you pop the can open, turning the tab around aligns the hole perfectly for a straw. This prevents the straw from floating or shifting while drinking.

While this wasn’t the original intent behind the design, it’s a clever and surprisingly convenient way to make use of an otherwise inconsequential design quirk.

If you're like me, this has likely been a brain teaser since childhood: What is the blue side of a two-tone eraser for? Popular wisdom says it's for ink removal, but have you ever tried erasing ink with that side? It just completely obliterates the paper.

Well, it turns out the blue side of a two-tone eraser was actually designed for use on heavier paper, not for removing ink.

The small bumps on the ‘F’ and ‘J’ keys exist to help typists find their hand placement without looking.

These tactile guides help your fingers find their way back to the home row, enabling faster and more efficient typing. Even if you're not a professional typist, you can rely on this feature to improve both speed and accuracy while writing.

Ever watched a monkey peel a banana? You might be in for a surprise, because it turns out the easiest way to peel a banana is from the bottom, not the stem.

Monkeys naturally pinch the bottom of the banana and pull, avoiding the struggle of breaking the tough stem. This method also reduces the risk of squishing the fruit inside.

The small hole at the end of a measuring tape is designed to hook onto nails or screws for one-person measurements. This feature provides a more stable grip when measuring long distances without needing an extra set of hands.

Also, the serrated edge on some tapes doubles as a tool for marking surfaces. So, next time you don't have a buddy around to help, don’t worry—your measuring tape has you covered!

Many people use the drawer under their oven for storage, but it was originally designed as a warming drawer.

This compartment keeps cooked food warm while the rest of the meal finishes, though in some modern models, it may simply be intended for extra storage. Checking your oven’s manual might reveal its true purpose.

Ever heard someone say you can judge a good wine by the depth of the indentation at the bottom of the bottle? Well, that’s a myth, though it may suggest a better-designed bottle.

The indent at the bottom of a wine bottle, called a punt, helps distribute pressure and maintain structural integrity. Originally designed to support the bottle against carbonation in sparkling wines, it’s now mostly tradition but still improves durability.

Things you never knew about lefties (but will enjoy reading)

Lefties make up only a small slice of the population, but they sure know how to keep things interesting. From wrestling with scissors to secretly beating everyone at video games, southpaws live in a world built for right-handers and still come out on top. Whether you are left-handed yourself or just curious about what makes them stand out, these facts will give you a fresh look at the lefty life.

Only about 15 out of every 100 people are left-handed, making them a somewhat rare bunch. Men are more likely to be left-handed than women, and family history also plays a role. If you want to find out how, keep reading!

Around one in five MENSA members, the society for people with sky-high IQs, is left-handed. Some scientists believe this may be due to the way left-handed brains connect information across the two hemispheres more easily. So if a lefty says they "think differently," they might be telling the plain truth.

This one may raise some eyebrows: Studies have found that left-handed men with a college education actually make more money than their right-handed buddies, sometimes 15% more, and up to 26% more for those who complete a degree. No one has nailed down the reason, but it could be their knack for solving problems in unconventional ways.

Mark your calendar: August 13 is International Left-Handers’ Day. It is a fun little holiday created back in the 1970s to celebrate life on the "other side." Some people spend the day using their non-dominant hand for everyday tasks, just to experience what lefties deal with all the time.

Left-handedness can run in families. If both parents are lefties, there’s a 50% chance their kids will be too. Two right-handed parents, on the other hand, only have about a 2% shot at raising a lefty.

Here’s a fact to share with your cat-loving friends: male cats tend to be "left-pawed," while females usually favor their right paw. So if your tomcat keeps swatting toys with his left paw, he is in good company. Turns out, even pets deal with a version of handedness.

Let’s be honest: the world isn’t built with lefties in mind. Scissors, can openers, and even desks in school are usually designed for right-handed people. Half of lefties give up and use a mouse with their right hand, and most use the "wrong" hand for scissors and knives. Lefties learn to adapt quickly, but it’s not always easy.

Here is where lefties really shine. Studies suggest they are better at processing lots of information at once, which comes in handy for activities like video games. Quick reactions, split-second decisions, multitasking… Lefties seem to have a knack for it all.

Lefties may be in the minority, but that hasn’t stopped them from shaping history. Consider this: Out of the last five U.S. presidents, three were southpaws—Obama, Clinton, and George H.W. Bush. Clearly, we can say left-handers have left their mark in big ways.

Interestingly, the older a mother is when giving birth, the more likely her child is to be left-handed. No one knows exactly why, but it adds another twist to the mix of biology and chance that determines whether a baby grabs a crayon with the left or right hand.
