The Hole In Your Lollipop Stick
The lollipop stick hole keeps the candy from falling off the stick. When manufacturers pour melted candy into the molding and the stick is added, some of the candy seeps into the hole. Because of this, the candy does not move when it hardens.
The Letter Arrangement On Your Keyboard
Computer keyboards are non-alphabetized because it is a remnant of the first keyboard, which was part of a typewriter. At first, the keys were in alphabetical order, but typists ended up typing really fast. This caused the key arms to become stuck, so they rearranged the keys. These days, everyone has gotten used to non-alphabetized keyboards, so perhaps nobody has gone back to alphabetized ones.
