Exploding cigarette lighter joke

When you lend your lighter to a friend, as soon as they take the top off there is a loud report. To set up this alarming joke, all you have to do is pull back the spring-loaded clip, put a percussion cap underneath, and then replace the top of the lighter so that the spring-loaded clip is held back. The lighter is now all ready to scare your friend.
