Liquify by Richard Sanders and Bill Abbott

Have someone concentrate on a thought.
Ask them to imagine their glass of water as a crystal ball and to focus their thoughts into it.
Tearing a corner from a piece of paper, you ask the spectator to dip the paper into the water.
Slowly and eerily...THEIR THOUGHT APPEARS ON THE PAPER!

Key Points:

• Absolutely nothing is applied to the paper.
  (No chemicals, no lemon juice, nothing)
• Absolutely nothing can be seen on the paper prior to the revelation.
• The paper is completely examinable before, during and after the effect!
