Startling ending to this one! Place a sponge hexagon in a spectator's hand. Touch the hand and magically, the spectator opens his hand to find that one sponge has become two sponges! Place two sponges in his hand, and they become three sponges! Finally, place the three sponges in the spectator's hand. Ask, "Do you think the three sponges have become four?" When the spectator opens his hand, the three sponges have turned into a sponge in the shape of a big "4"! The three sponges have literally become "4"!
Use this as a fun counting lesson for a child.Use this trick with another sponge trick, like the Big Red Hand. Do this trick first, then repeat the first part of it. Of course, your spectators will say "Oh, we know you have a big 4 in your hand". You say "You caught me red-handed!" and produce the Big Red Hand instead. A nice surprise ending to your routine!
The name of this trick is a reference to Agatha Christie's most famous mystery novel, And Then There Were None.
