This one is super- you may even fool yourself!
Make a borrowed quarter lift off a Bicycle backed playing card! Show a playing card on both sides, then place the borrowed quarter on top of the card. At your command, the quarter rises off the card at a 45-degree angle, then returns to rest on the card again. You control the speed, and you can repeat it over and over.
No, it's not done with magnets or thread!
Quality made effect, in Bicycle poker size to match regular decks. Comes complete with special card and instructions.
