How do Magic 8-balls work?

Have you ever played with a Magic 8-Ball? They’re black and white toy balls – but with a twist! People ask the Magic 8-Ball a question, shake it, and it gives you an answer!   How do these toys work? And when were they invented?  We asked Chris Bensch, head curator of the Strong Museum of Play in Rochester, NY to help us out.
