I love the Ein-O science toys and kits. I played with this one recently and was surprised at the number of cool science projects and experiments you can do with it. The experiments are: making a hoverball, creating a sticky beaker, magic jumping beans, building a simple water filtering, twin rings, connecting water, paper kite, can roller, frequency match, and a suspended paperclip. It’s available wherever great educational toys are sold.

Or you can find it at Atomic Elephant Toy: Ein-O Top Test Tube Cool Experiments.
