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.

 

 

The name of this trick is a reference to Agatha Christie's most famous mystery novel, And Then There Were None.
