Predicta

You show a sealed envelope with a prediction inside. You ask a spectator to name any four numbers from 0 to 100. To memorize these numbers, you write them on a piece of paper. Hand the paper with the numbers you wrote to the spectator, tear open the envelope, and hand it to the spectator- inside s/he will find a lottery ticket (scratch and win type). You ask them to scratch it and amazingly the numbers match! No force, no influence, any four numbers and it matches every time! Includes instructions. Very good condition.
