TOP SECRET: See if you can figure out the forces that keep this top spinning for up to a week!

It's not quite as simple as you would think. Just give this top a gently spin and it will increase speed and stabilize; seemingly all on its own. The fun is in trying to figure it out. Each Top Secret includes a complete science explanation. Base is powered by a 9 volt battery included with the set.
