I like all of Steve's videos, they're really good.
"The Golf Ball Paradox": throw a golf ball (or squash ball) into a cylinder and it pops back out (without touching the bottom)

And I am so with him on the fact that *anything* around rotation/gyroscopic type motion is a tough one to intuit!... follow the math, sure... but "understand it "intuitively"... argh!! Easier (for me) to intuit ideas in relativity and quantum. 😀
