This is a prank involves Styrofoam cups filled with water and sugar over a door tilted slightly against the wall so when the victim opens the door the cups fall onto them. The victim doesn't only get wet they get sticky. This is a very simple prank and all you need is Styrofoam cups, sugar, water, and a door that opens inward. Fill the cups alternating between water and sugar. Then place then on the top ledge of the door. Slightly angle the cups against the wall or tape them to the wall. Then wait for you victim to push the door open and the cups of sugar and water will fall onto them. Be careful who you plan on using this prank on and attempt at your own risk. It is also very messy and not fun to clean up but should get a pretty good reaction.
