A tiny sponge ball appears from nowhere, growing and multiplying at a snap of the fingers. Two spectators are pulled in and asked to squeeze — and each ends up holding a ball that was never placed in their hand. The count keeps climbing, one ball at a time, until three people are holding sponge balls that seemingly appeared from thin air. Then a final spectator gets to choose, again and again, which ball vanishes next — and no matter what they pick, the balls keep disappearing into thin air. Nathan Kranzo's Sponge Balls routine — watch it and see why it's one of the best reactions in magic.
