Happy Feet

Nice demo! Thanks!

Spoiler: Question

So under rotation condition B is not electrocuted?

What?? I don't know how you did that, but it was a fun surprise.
Maybe something more can be done with that?
Anyway, well done

Nice design with a nicely hidden mechanism.

Interesting.... Thanks

Looks like helpful one... btw interesting demo

Nice demo

Interesting trick!

@chemi Yes and no.
I put a motor on B's head and attached it with the floating R (you know, when you put a motor under R) so somehow B was lifted by air a bit.

Good first demo.
