Show a deck of cards. So you can’t do anything sneaky with them, you place them in a paper (or styrofome) cup. Upon your command, the queen rises out of the deck! Would you like to learn to do this one? Before you start, poke a secret hole in back of the cup, near the bottom. Make it just large enough to slip in your first finger. Have the queen on top of the (face down) deck. Now you’re ready!
Set the deck in the cup (queen next to the secret hole). Hold the cup at the bottom in your fingers, as your first finger secretly slips in the hole from the back and pushes up the queen–upon your command!
Practice this a few times in a mirror. Then try it out and let us know how it goes! Good luck!
