Teeth Loss

Get some pieces of gum and a tomato. Squeeze the tomato so the juice comes out onto the pieces of gum. Put the pieces of gum in your mouth. Don't worry, you aren't supposed to chew them. Get someone to come into the room you're in. Run into a wall and then fall on the ground. Let the pieces of gum fall out of your mouth and onto the ground. The victim will think that you lost a tooth.
