Detachable Car Headrests
We’re guessing you have to sit in the back of the car as well for road trips. That was about the only thing you could think of to do other than toy with the headrest right in front of you back then! Who would have believed you’d be able to get it out in the first place? This was done by car designers to ensure that the metal bars would be able to shatter the windows in an emergency.
Solo Cup Lines
You should be aware that red solo cups are not only useful for beer pong. There are actually horizontal lines that will tell you how much alcohol you are consuming in a given amount of time. The first one refers to a single shot or an ounce of something. Two glasses, or five ounces, is what the second one is. One whole bottle, or twelve ounces, is required for the last one.
