Needed – Cayenne Pepper. Electric Cooker.
This is a very good one. Sprinkle a good dose of the pepper on the ring element. Turn the ring on and leave the room, shuting the door behind you with your friends in the kitchen not looking at the cooker (this is easy if you have a joint kitchen living room, wait till they are watching TV). This will result in the pepper burning into the air and your frends eyes streaming and throats burning.
