The magician shows a realistic-looking voodoo doll, and places it in the spectator's hand to view. It is just a little straw doll. When the magician lays the doll in his own palm, it suddenly comes to life - it rises like a mummy out of a casket and stands up straight! Spectators will believe that an invisible force is making it rise up and down. This looks insanely good!
The doll is completely under your control. No wires or threads.
