"Please tell me that's for sale!" Martin Sanderson

You show five small balls to your audience, one black and four white. They're dropped into an opaque bag which is then shaken by an audience member to ensure that the balls are well mixed.

One by one five audience members remove a ball concealed in their hand. Despite the thorough mixing and random distribution of the balls you can instantly tell who holds the black ball!

Can be repeated over and over again and perfect for parlor, stage, or the strolling magician!
