I ordered some silicone molds that make perfect ice spheres about the size of a baseball. I put them in the freezer and out came the ice balls for juggling. I went outside and tried them out.
I was able to do it – and of course my hands got very cold! The balls began to melt and in turn got slippery. But I could still maintain the juggle for about a minute or so. Maybe my next trick should involve some sort of mix of juggling these with fire torches. The fire and ice show. What do you think?
I can see some good teaching opportunities here too, such as the nature of water and how it can take on different properties. And how the hands are very warm and have the potential to melt ice fairly quickly.
