Here is the perfect climax to your sponge ball routine.
You show a red 50 mm sponge ball. Slowly and very clearly, you push the ball into your empty hand. When you open your hand again, the ball has transformed into a giant (100 mm) super-soft sponge ball.
It looks pretty amazing!
In the video, you can see another way of performing the trick, where a black and a red ball are pushed together into the hand, transforming into one giant red ball and several small black balls. This version requires that you already have a 50 mm black sponge ball and some matching small ones. These are not included.
