Diminishing Sponge Balls by Magic Ian, originated back in 1979 and received 4 stars in Genii magazine. Frank Garcia acknowledged that it was one of the few new sponge moves he had seen in years, and Goshman himself loved the effect.
The 23 minute Mini DVD has a several routines, unique setups, suggestions for use with all of your sponge props plus easy to follow instruction.
Effect: The magicians shows 3" sponge ball, and splits it visibly and without cover into two 2" sponges. Then, one of the 2" ball is split into two 1" balls, and finally, one of the 1" balls is split into two .5" balls. The last ball is transformed into a 3" ball. This effect can be combined into any sponge ball routine plus you can use it with the ball to bunny or ball to square effect.
It had been off of the market since the late 80's, and now comes to you in a special limited custom run of DYE-LOT matched, SUPER SOFT Goshman sponges.
