Alright, we definitely aren’t expecting you to be paying attention to brass doorknobs, so if you haven’t noticed this next one, then you get a free pass. All doorknobs are made out of brass. There is a very smart reason for the doorknobs being made from this, and it is surely not an accident. Things made from brass hold up better against bacteria build-up. Think of the number of times a day that doorknobs are touched.
The brass helps make them free of germs. This is very important, considering that people are constantly touching doorknobs after touching a load of other things. Obviously, this is important since people will pick up germs on their hands in countless different ways. Thanks to the brass, we are less exposed to germs than if they had been made from another material.
Extra Fabric With Clothing
You've probably noticed when changing your clothes, that a lot of them come with an extra patch of fabric inside. If anything, you've thought to yourself that the fabric is there in the case that your shirt or pants rip and you need to do some sewing. Well, it's not there in the chance that your pants rip, although we suppose that you can use it as such if your shirt does rip (note that this might look very obvious unless you're a professional seamstress).
The little fabric's true purpose is to allow you to test out washing the material a certain way, so you know if it'll shrink or if the colors will bleed. This addition, which is nothing short of genius, lets you know how the clothing item will react in the machine. If you're hitting yourself now, just remembering the last time you ruined a new shirt, don't feel so bad. Unfortunately, this is a feature that most people don't know about.
Three Handles on Jerry Can
Jerrycans were designed in Germany in the 1930s for military use. The original design of the jerrycan still remains in widespread military use. The three handles were designed because it was specified that a soldier should be able to carry two full containers or four empty ones by holding onto the outer handle. In order to keep the fuel evenly distributed while you're holding it, there are three handles across the top.
This is especially true if two people are carrying it. If you are holding it with a friend, you should each grab one of the outer handles. If you're Hercules enough to carry it on your own, then grab it by its middle handle, or if you're carrying two in each hand, then by its outer left and right handles, respectively.
The Fifth Pocket on Your Jeans
Surely you've noticed that little pocket on the side of your jeans, and while you probably just chucked its existence up to a design choice, and use the tiny compartment for storing folded cash or your trusty lip balm, this fifth pocket actually has a purpose.
Jeans used to be the preferred type of pants for cowboys and gold miners during the mid-1800s, and one of the most valuable items they carried around with them was their pocket watch. The tiny pocket was designed to keep their expensive and delicate pocket watches free from harm while they worked.
The Hole in a Pasta Spoon
Have you ever noticed the big hole in the middle of your pasta spoon? Even if you're not a big fan of Italian food, you must have seen these spoons at least once in your life and wondered why on earth would a spoon have a huge, weird hole going through it. As it turns out, there's a very simple and neat reason behind it - to help you calculate the exact amount of pasta you need for a single serving.
So, next time you're cooking just for yourself and don't want to overdo it with the carbonara, just take a handful of dry noodles and fit them through the spoon hole to make sure you have the right portion.
