The classic trick allows you to place a ball on the edge of a tube and on command, allow the ball to lower and raise into the tube. THEN pass the apparatus for examination. Originally known "hypnoball" used by mentalists and hypnotists, this is a versatile and well made prop. The book teaches you to produce a coin, sponge, fire or liquid from the tube. Produce several balls from the tube then vanish them back, hand out a solid tube as a finale, plus a no gimmick ball and tube routine guaranteed to baffle the "in-the-knows."
