Do you even lift?

Shoebox Joe - 2013-03-30 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.

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.

Bort - 2014-08-22 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 - 2014-08-23 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.
