Description
This classic effect is straightforward and simple:
The magician reaches into his pocket and removes a brown pay envelope. He removes three cards which are printed with large circles on them -- one red, one blue, and one yellow. The cards are placed face-up on the table. The magician asks one of the spectators to mentally select one of the colored dots by touching it with a pen. The spectator reveals their selection, and the magician reveals he was right!
