Coke Machine Hack
Have a couple of dollars and three friends, yet you are all thirsty? Not a problem. Go to a coke machine with the arm that slides up and down threw the glass (picture below) and insert your money. Then when it is about to give you your coke, place your hand inside of the hole (where you collect your coke) and hold the trap shut. If you do this you will be able to obtain more cokes FREE! Each time the bar comes up to give you your soda, simply hold the trap shut until you have the right amount of cokes for your friends.
