The Turntable Paradox

[Retro]

What happens when you put a ball or disc on its edge on a rotating turntable? Clue: it doesn't fly off like a penny laid flat on it would.

Fascinating physics demonstration by Steve Mould that a lot of people won't know about.

Nerd level: high.

OMG!! That is so cool! Very interesting on how you can manipulate the ball to stay in place and match the speed of the turntable too. I would have liked to know about this example in physics a long time ago....might have prevented some unexpected flying projectile calamities in my real life.

Oh do tell!

I actually didn't know that the system would behave like this. I thought I knew all the basic physics there was to know, but there's clearly more. Would be fascinating to learn about other new things like this.
