A TERRIFIC routine for kis, especially at parties!
Show your "Educated Block" of wood. The kids are not impressed.
Claim that he can do tricks. The block sits and stays. The kids are NOT impressed.
Then the block hang impossibly from the rope, moves on command and stops. The kids are VERY impressed!
With a knot tied through its center, the block magically penetrates right through the rope, right in plain sight! The kids go crazy and the parents write you a check.
MADE in the USA!
