BeyBlade Science Experiment

My son, 8yrs old - 2nd grade, LOVES Bey Blades so we thought it would be neat for him to do his yearly science experiment using BB's. He wants to show how BB's produce air currents or show how BB's spin differently (impact on RPM's) based on weight - basically we want him to be able to explain momentum, inertia, all that good physics stuff by using BB's (even if it's high level).
Just wanted to know if any of you out there come across or have done any science experiments using BB's. Please let me know and send me links to articles, videos etc.

Thanks WBO

Anyways, sounds cool! Welcome to the site! I do not know whether or not this thread will stay open, as it could essentially go in Beyblade Random Thoughts. Or additionally could serve as an intro thread after being moved in the proper section, but eh I will post anyways XD

Here are some relevant threads:

For air currents you could use the steam produced by dry ice inside a beystadium. Then spin a beyblade in the fog! This will most likely cause the fog to spin as well
