A message of your choosing appears instantly between two miniature slates. No sleight of hand. The spirits are your aides. You simply show the slates on both sides - no funny moves - and then place them together. When shown again, a message from the spirits has appeared on one of the slates, written eerily in chalk. Any message that fits on the slates works here. Perfect for revealing chosen cards, the contents of a center tear - whatever you desire. A classic trick.
