My old Physics teacher’s best day was when he was demonstrating gyroscopic precession.
He sat on a stool with a bicycle wheel with handles. After spinning it up to speed, he rotated left, and then right, with no effort involved.
It looked like a lot of fun.
Yes ,remember that.
The class later demonstrated the theory of ‘advanced mass entropy’ with Gyroscopes.
Spin the thing up on a bit of an angle.....Woooooooshhhhh!!
Did you ever experiment with Gyroscopic propulsion? Small wooden carts everywhere!
A quarter of a century ago now, but still causes a big grin.
