Chemistry I classes created Cartesian Divers that would sink and float to the top of a water-filled pop bottle when you squeeze the bottle. The concept demonstrate Boyles Gas Law where increasing the pressure on a gas lowers its volume. It also shows how bouyancy and density can affect the diver. Amazingly, you can use a Heinz ketchup packet as a diver as well! Here are the winners of the diver races and some pics of students making them in lab.
