The colour change sponge ball can be added into your current sponge ball routine or just used by itself to create super visual magic.
Take a close look at the ball. When turned inside out it changes colour. It is very easy to make it change colour with just one hand....
Show the ball and as you place it into your other hand you then use your thumb to push it inside out. Be sure to make sure when you reveal the colour change that the sponge ball secret is not exposed.
