About a month ago I went to Disneyland with a bunch of entertainers after an event we were all at. While not everyone was specifically a magician, everyone there had a magic component in their show. Somehow the “10 Count” with sponge balls came up.
The 10 Count is a little thing where a sponge ball travels from one hand to the other while you count to ten. Each number has a physical action associated with it. It’s a great framing for a quick trick and isn’t limited to sponge balls. I first learned the 10 Count from a sponge ball book when I was a teenager, however it looks like it was probably created by Martin Gardner using matchsticks.
If you don’t know it, it’s worth looking up!
