Aluminum Foil Packaging
Ever notice the tabs on the side of aluminum foil that you can push in, but you were never really sure what they were for? They’re actually really useful! When you push them in on both sides, it actually locks the roll into the box so it can’t move around when you’re trying to rip off some foil. Useful!
Half Belt On Jackets
This style is generally seen on trench and pea coats. What is it for, though? They were originally developed for men in the military who had oversized jackets that doubled as blankets. The half belt was used to gather the extra material and hold it in place so soldiers could walk freely. Nowadays it’s just used as a fashion trend, but at one point they had real use!
