Spinning balls

I'm still puzzling over how they hold onto their angular momentum.

It's not like they're aerodynamic, in fact the only thing they have going for them is that they'd be extremely well balanced.

Hmmmm.

Without video... we have no proof that Metalicas stage could be sucked into the vortex... will need video of the homemade versions.

Where's the vids?

Sorry gentlemen. No vids of Metallica at this time.

They are shooting at the shows for a movie and it is strictly against company policy blah blah blah.

Here is the drum "mobilator" that we built.

It's remote controlled with 4 pneumatic mobilator drive units. It can move in any direction up to 2 fps and weighs a gazillion pounds.

Only reason I am posting this picture is because it is up on Metallica's website.
