Grand Illusions is offering what they call a Somersaulting Top:
https://www.youtube.com/watch?v=oFT28gJnIeMIt is actually a shorter version of Philippe Dyon's ball top and not nearly as impressive. I need to record a high speed (slow motion) of that top. It starts as a very high center of mass top and because of the balancing holes the spin should be easy to follow.
We have seen many videos of Tim showing off tops, but I don't think this one was posted. Tops are just at the beginning. I can say that I've got a bigger top than Tim has!
