15 Ordinary Items With Hidden Functions or Meaning That You Didn’t Know So Far

Nowadays we don’t think too much of the function of all the designed pieces that we buy. We just accept the fact that the designer wanted it styled that way. And maybe some things are not meant to have a certain function, just to be there for aesthetic purposes.

However, before everything had a meaning. A lot of designs that have survived from the past, had an actual purpose, and some of the will surprise you. Therefore, this article will enlighten you about ordinary items we use but never knew the whole function of.

Scroll down below to check designs out and learn more about their history.

The little arrow-like symbol on a dashboard. It’s not only you who, upon arrival at a gas station, has had to work hard at remembering which side your gas tank is on. It turns out, the answer has been right in front of you. Every dashboard has a little symbol—an arrow or a triangle—placed near the gas gauge. It indicates precisely that which you forgot: which side your gas tank is on. If the arrow is pointing left, look for the filler cap there. If it is pointing right, you know what to do.


Aside from the obvious use for buttons, you might have wondered why the ones women’s shirts are on the left. Especially when you consider that most people are right-handed. Turns out, putting the buttons on the left of clothes is an old tradition carried over from a time when buttons represented your social and financial status. If you owned buttons, you probably were being dressed by a chambermaid, and the buttons on your left were on her right when she was facing you.



The holes in the handles of utensils. Although, they’re great to hang your pan or pot on a wall, they’re also perfect for holding spoons and ladles while cooking. That way, you won’t get your kitchen counter messy!


Have you ever wondered why keyboard letters are arranged the way they are? To find the answer to this question, we need to take a look at the first keyboard ever invented. It belonged to the typewriter. Originally, keys were arranged in alphabetical order but typists got so good at their job that they would end up typing too fast and the key “arms” would get cross-wired and stuck. So, keyboard manufacturers had to randomize the order of keys to intentionally slow down typists to keep the machine running, and we haven’t changed it back to this day.


In the 1970s, cleaning the mouth to keep it healthy wasn’t enough; people wanted something in the toothpaste to freshen the breath, too. Aquafresh answered the call by adding in a blue stripe to their paste to indicate that it could do both. After people began paying more attention to the health of their gums, the brand added a 3rd red stripe to their product, indicating that their paste now had triple action; cleaning, freshening, and plaque control. Even though solid white toothpaste offers the same benefits, companies continue to add stripes to their paste because it still sells.


The half-belt on coats and jackets. Nowadays, half-belts are added to clothes mostly for the sake of style. However, they were originally used on oversized military jackets that doubled as blankets to gather up all the extra material so that soldiers could walk without stumbling.



The number “57” marks the spot where you can tap the bottle to make ketchup come out of the bottle easier.

The tiny buttons on your jeans. These buttons are known as rivets and they’re the silent heroes that make your pants last longer. They’re placed in the areas that are most likely to tear from movement or strain and help hold the fabric together.



The holes in pen caps. Some people can’t help but chew the caps of their pens (tip: don’t do this). However, it’s a potential health hazard because you might swallow it and choke. The holes in the caps allow people to breathe in case that happens.

The delicious Toblerone candy bar was first manufactured in Switzerland, so it is easy to see why people assume that the odd triangular shape of the candy bar is a shout out to the Swiss Alps. Actually, the design of the chocolate bar is all about function, not aesthetic. The pieces are in triangles so that if you press on one of them with your thumb, it will snap off easily and leave you with the perfect sized serving.


You may have noticed that a lot of denim jeans come with a tiny extra pocket on the side known as the fifth pocket. While millions of people have found thousands of different uses for it, from storing folded up cash to tucking away a stick of lip balm, this small pocket was actually designed with a very specific item in mind; the pocket watch. Jeans were the pants of choice for gold miners in California in the mid-1800s, and one of the most important items they kept on them was their pocket watch, which was generally delicate and spendy. The fifth pocket was designed to protect their expensive pocket watches by keeping it snugly and safely tucked into place.


Have you ever found yourself wondering why the edges of dimes and quarters have rough-hewn edges, but the edges of nickles and pennies remain smooth? Well, you are right to wonder, because there’s a very good reason for this. Back in the good old days, coins were stamped from different types of metal cast in different weights that were the true value of the coin. For example, one silver dollar was crafted out of one ounce of silver. People began shaving off the edges in coins to save up to melt into new coins later and would spend the shaven coins at their full value, even though they weren’t worth that much anymore. In order to avoid this, coin minters started using the rigid pattern only on the precious metal coins, so that a person could easily tell if a coin had been shaven.

13. The loops in the frame of a grocery cart

While even our checkers and baggers don’t know it, there is a purpose behind those metal loops that frame the top fold out section of our grocery carts; to hang your bags with light items like bread and eggs from so they don’t get smashed among your heavier goods. Do your grocers a favor and show them how it’s done next time to make their lives easier.


Remember the horror of realizing that “college ruled” notebook paper meant slimmer margins, and therefore left room for more writing? Well, believe it or not, those margins weren’t invented as a guide for how many sentences you could fit onto one page, or even to leave space for note-taking. Manufacturers began to apply margins to writing paper for the purpose of protecting your work. Earlier on in history, rats were a common resident in many people’s homes, and one of their favorite snacks was your paper, in addition to everything else they could munch on. Applying wide margins to paper safeguarded against losing important work by leaving blank spaces around the edges for the rats to chew through first, and to protect the writing on the outer edges from general wear and tear.


The brushes on the sides of escalators aren’t for polishing your shoes. You may have been using these escalator brushes to clean your shoes, however, these bristles are actually a big safety feature. One of the biggest reasons for escalator mishaps is people getting their clothes and bags stuck in them when they stand too close to the sides.

These nylon bristles play with your mind and make you keep your feet away from the escalator’s skirt panels, hence avoiding accidents.
