Creating traps around the house to injure and amuse friends and roommates is one of the best and most common ways of performing a prank. In this video, you will learn how to turn one overused household prank as a decoy for a more insidious one. First, you stretch an obvious decoy trip wire across a part of your house with a hard floor, preferably tile. Then you grease (with butter, lotion...) the floor on the other side of the wire from where you expect your victim to enter. Then watch as they mock your trip wire only to step over it and stack on the slippery floor.
