Removable car headrests
Perhaps you have sat in the back seat on family trips. Out of boredom, you probably played with the headrest in front of you. However, you may not have known that you can remove the headrest from the seat. It has been designed so that the metal bars can be used to crack the window in an emergency!

Red party cups
Who doesn’t know these Solo cups? Many people have some sort of memory with these cups, but perhaps few really know what the horizontal lines on them are for. For those who have no idea what the ridges are for, they are designed to indicate how much alcohol or drink is in the cup! The first line tells you that there is one ounce of booze or one shot. The second line tells you there is five ounces of wine. The top line tells you there is 12 ounces of beer.
