“57” number on a Heinz bottle

The number “57” on a Heinz bottle. Apparently, the embossed number “57” on Heinz’s bottle is what the company’s spokesperson calls a soft spot. “All you need to do is apply a firm tap where the bottle narrows and the ketchup will come out easier.” No need to punch that bottle too much!

Why keyboard have bumps with ‘F’, ‘J’, ‘5’ keys?

The ridges on the “F”, “J” and “5” keys on the keyboard. They help your fingers find their location on the keyboard. This way you can type without having to glance down much easier.

Random Letters On The Keyboard

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.

Pom Pom on Sweaters

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Now they are outdated and so you can see the way in lifehacks about how to remove Pom Poms… haha

Stripes on your head or earphones

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. Mostly they are dark like rings that might look like they are for decoration. They are there to protect the wire that transmits sound to the headphones. They are usually two to three rings one for the left headphone and the other for the right and the other is neutral.

The hole on the pen caps

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.

Lollipop and pipe like a hole

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.

Besides, 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.

Plastic disk/ring under bottle cap or on the top

Most people see it and they do not know its purpose. They help to keep gases in the drink intact and avoid it from escaping and prevent air from outside from getting in.

Half Belt on the coat

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.

Double color erasers

The different-colored sides are used to erase marks made by different pencils on different types of paper. While the soft pinkish-orange side is used for light grades of paper and light pencil marks, the blue side is meant for grainier, tougher paper and darker marks. The blue side was later promoted for removing pen marks because a lot of people didn’t understand what it was meant for.

Long bottlenecks

The shape of a beer or a soda bottle is so familiar, nobody would think twice about it. But it turns out this long bottleneck is shaped this way on purpose. According to “Interesting Engineering”, such a design allows packers to seal off the top with a small bottle cap, reducing the size of the seal and thus saving money. Plus, it is practical, since a small seal on a beverage container is stronger and more reliable than one which covers a larger area.

ToothPaste

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 hole on Measuring tapes

The little slot at the end of the 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.

Eyelets on shoes

If you loop your laces through them, then you tighten the shoe around your ankle and prevent the shoe from moving around. This way you increase the stability of the shoe, decrease impact loading rates and prevent your foot from moving about while climbing or descending hills and trails. It’s great for jogging and hiking!

The real purpose of these tiny things you see daily will amaze you…

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, 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 to protect your work. Earlier 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.
