Three Shell Game

Effect :

The spectator can never find which pea the shell is under

Secret :

To do the three shell trick you need three walnut shells and a foam rubber pea.

The secret it when you put one of the shells over the pea the shells have been shaved a little on the back.
You apply some downward force while you slide the shell forward and the pea comes out the back.

This is the secret. To do the trick you put your fingers on the shell just right so you can catch it. Then you
squeeze it a little in your fingers and the audience can't see it. Then you pick up another shell and slide it forward
and over then back and let go of the pea when you move it back. The pea will then be in a new shell.
