Things With Hidden Features That Probably You Didn’t Know

If you're curious about the "world of fashion" like we are, then you've probably wondered about those tiny squares of fabric with buttons in small Ziploc bags that come with new clothes. 

Of course, you can use the button to replace a missing one and you can use the piece of fabric to patch up a hole. But the main purpose of the fabric swatch is for you to test out different cleaning products on it so you won't ruin your clothes.

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.

They were invented by Jacob W. Davis, a San Francisco tailor who found himself constantly repairing the clothes of workmen. They would come to him with ripped and torn pockets, hanging open, and his solution was pretty ingenius – he stuck them shut with copper rivets to stop them coming open so easily. 

Davis knew he was onto a winning idea, so in 1870 he approached a little known fabric supplier called Levi Strauss (sound familiar) to help him pay for the patent and to set up his own business producing work trousers with riveted pockets, made from denim cotton.

The sturdiness of the newly riveted pockets was a huge selling point for workmen in San Francisco, and once the rest of the country caught on, history was made. Davis’s prototype is the foundation for jeans as we know them today, so you have him to thank for your favourite pair of skinnies.

Brass is the best metal which keeps bacteria away! So that can be used as germ proof solution. Perfect in a household with lots of kids.

The pom-poms on beanies and other hats. They might look cute and fluffy now but they had an actual function before. French sailors used to wear hats with pom-poms so that they wouldn't hurt their heads on the ceilings of the ship during rough weather. 

Now they are out dated and so you can see the way in lifehacks about how to remove Pom Poms... haha

The first is the stripes on your headphones or earphones jack- these mostly are on the jack that you enter into your phone or music devices.

Most children see that hole as a whistle since it produces sound when air is blown through it. The purpose of the hole at the end of the stick is to prevent a person from choking accidentally by the sweet.

In addition, This weird little hole emerging after you finish a candy has been bugging us for years. Who would ever put a whistle there if it doesn't work?! It turns out, the reason for this lollipop stick hole has to do with manufacturing. When pouring hot, molten caramel into the mold, some of it seeps into this hole and hardens. It allows the candy to stay on the stick and not to fall off.

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 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.

You must show the margin on the notebooks or Microsoft Word or other pages. Right?

When you view your book, there are always margins on your far left and right, mostly a red line that separates them from your work. Most people believe it is left for corrections, for numbering or rough work but the main purpose is to prevent your work from damage by animals such as rats that feed on book edges.

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.

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 little slot at the end of measuring tape. Most measuring tapes come with a metal stub with a small slot on the end. In case all your hands are full, hang the slot on a nail for measurement. If you look closely, you will also notice that the stub is slightly serrated on one side. It can be used to mark the points without a pencil.

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.

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.

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.
