Show a mighty colorful wooden cutout of Howzzat The Clown. He stands about 18 inches tall and is silk screened in a zillion bright colors. In Howzzat's left hand is a top hat. In his right hand is nothing. For the moment. From a shuffled packet of cards, have a kid select one card. Hand the kid a crayon and have him sign the card. If you are working for little kids, you can use Alphabet Cards or Picture Cards. Have the kid replace the card in the pack, shuffle the pack and place it inside the top hat. Now, blow up a balloon and attach it to Howzzat's right hand. The fun begins. At your command, Howzzat tips to his right. The balloon bursts. And, the selected card appears in his hand. It looks wild. It's as if he tossed the card from his top hat into his other hand. totally visual.
