Tenyo Floating Card
Show a deck of cards. A spectator draws any card. Place this on top of the deck of cards. Suddenly the card takes off and is now floating freely above the game, about 5-6cm high. With a second card you drive between the floating card and the rest of the game and prove that there seems to be no connection anymore.
Tenyo has improved a familiar effect into an excellent execution. The tool is not earth-shattering but interesting nonetheless.
