Things You'll Need
Instructions
Fill a plastic bucket or container at least half way full with water.
Open the door in the doorway where you want to set the booby trap. Choose a doorway that the intended victim is likely to use. Open the door no more than one to 1-1/2 feet wide to allow the trap to be set.
Use a step ladder or chair to stand in and raise the water-filled container up to the top of the door.
Place the plastic container on top of the door. Position the container in the middle of the door's top edge.
Balance the container on the top edge of the door. Position the container slightly toward the door frame so that when the door is opened by the intended victim the weight will cause the container to fall toward rather than away from the intended target.
