physics teacher sent me here

Thank you for posting this. I use to do this when I was a boy, 35-40 years ago. I wanted to show my daughter but we came to youtube first to see if anyone had posted a video on the subject. Well done! Lexi (age 9) thought you were amazing and magical!

Why does it work even when you spin it in the opposite direction and the curved hook is supposedly not pushing the coin? See kzfaq.info/get/bejne/e919dJRevZ2yZHk.html Why doesnt the coin slide off? It is following the hook!

Okay at first it was cool, then it blew my mind when he stopped it. True black magic aka physics
