Do you even lift?

This man is a golden God. Stars and Kisses, Shoebox.

Is that compliment directed at me or the man with the wheel?

Thanks either way!

Neat!

I like the little rock star leg kick at the end.
Bort
HOT!

Write that down in your copybook now.

You could write a hundred Silver Age Superman stories around the principle that things get lighter when you spin them.

So what's going on here -- the torque required to tilt the wheel is greater than 40 lbs, so angular momentum beats gravity? I'm also guessing the long axle lets the wheel travel through a long path as the guy spins around, meaning only a tiny bit of force gradually applied is enough to lift it.

That's my guess as well, yeah.

Sorcery. Sorcery and demons is what done it.

Bort
You know captain, every year of my life, I grow more and more convinced that the deal here is basic mechanical advantage. The spinningness of the wheel has two effects: it renders the apparatus essentially tip-proof, and it forces the wheel to travel in a big circle. So that means that, when the guy lifts the apparatus 12 inches, in reality the spinny part has traveled a much longer distance along a corkscrew path. That's textbook mechanical advantage: it's as if the guy were pushing the wheel up a long, corkscrew-shaped incline.

If you just take the time to look at it.

Bort
Oh, apparently that's not either. The trick is that he's pushing the thing "forward" as he releases it, and when you try to speed up the precession of a gyroscope, it responds by rising:

Another counterintuitive result, brought to you by science.

This is so fucking cool that I can only imagine Spaceman Africa created six new accounts to vote it down with.
