Or why all jeans seem to have randomly placed metal studs? There are so many little details that we overlook when it comes to everyday objects. Sometimes we assume that they have no purpose at all, and that they exist for purely aesthetic reasons. Other times we guess, correctly or otherwise, at what they might be designed to do. More often than not, they do have a specific purpose or use, and it is simply that we are ignorant of this fact. We’d bet that these are 12 things you didn’t know the purpose of; 12. The Stripes on Your Headphone JackThe rings on your headphone jack are neither for decoration nor grip, as some people may assume; they are, in fact, sections of insulation designed to protect the wiring that allows sound to be carried to both headphones. 11. Nail CuticlesIf you pay any attention to your nails and hands, you will most likely know what your cuticles are. This hard strip of skin at the bed of your nails may seem to be a useless chance of nature, but in actual fact, they are key to the health of our nails.10. Notebook MarginsBelieve it or not, the purpose of the margins in your notebook has nothing to do with getting criticisms from your professor or notes from your editor! Certainly, the margins are now used for noting corrections or making suggestions, but this was not always so. Historically, books and notes were most likely to be damaged by rodents9. The Plastic Disc Under Your Soda LidThat little blue disc of plastic under your soda cap? It’s not just there to print codes or prize giveaways on; it’s a pressure seal that performs the vital function of keeping the liquid and gas in, and the air around you out. 8. The Raised Bumps on the “F” and “J” KeysTake a look at your keyboard. You may have noticed that the F and J keys have raised dots or bumps. If you spend a lot of time using a computer, you will definitely have noticed, but you may not know what they’re for. 7. The Diamond Shape on Your BackpackThose diamond shapes on your backpacks are also known as lash tabs, lashing squares, or pig snouts! That’s right – they have a name and a reason for being there. Lash tabs are not just included in the design for decoration; they pay homage to a time when backpacks were mostly used by hikers and climbers.6. The Hole in Your Chupa-Chups StickThere is more than one theory about why the hole at the end of the Chupa-Chups stick exists. Some people say it’s there to counteract a potential choking hazard, others that it’s there for children to whistle through once they finish. The truth is a little more mundane (though close to the first speculation). 5. The Hole in Your Ballpoint PenIt’s common knowledge that the hole in the lid of your ballpoint is to prevent choking should you accidentally swallow it, but what about the hole in the middle of the pen shaft? Have you noticed that before?4. The Blue and White ErasersEveryone heard that the blue half of these erasers was meant for “rubbing out” ink. Of course, when we tried it, the eraser did little more than smudge the ink and ruin the paper. So, what is that blue half of this eraser for? 3. The Soft Inner Lining of Your UnderwearSo, you’ve probably noticed that there is a second lining of a sort in your underwear. This secondary lining, made of soft, tissue-like cotton, is called a gusset and is required if underwear is to meet the necessary health standards. 2. The Unexplained Studs on Your JeansHave you noticed the metal studs that seem to randomly dot the seams of your jeans? Well, they too have a specific purpose and history. When Levi Strauss first began making jeans, they were primarily worn by miners and farmers; manual laborers, in short, were his main consumer base.1. The Thick Cylinders Found on Electrical CablesThe correct name for these nifty little guys is “ferrite core” or “choke”, and they are not just a design feature with a mundane or purely aesthetic purpose; they have a very important, very high-tech function. So, did you know the function of these 12 everyday items, or was this as much of a surprise to you as it was to us?
