Description
Growing Ball Outdone: You show two sponge balls, one red and one black. You push them into your clenched fist. When you open your hand again, the red ball has grown to at least twice its original size, while the black one has multiplied into quite a few smaller balls. A great visual effect that’s easy to make. Complete with instructions in English.
The red and black ball is approx. 5 cm in diameter. And the small black ones about 2 cm.
