So, there has APPARENTLY been some confusion amongst some people about how particular amusement park rides work. So, to clear up that confusion, I thought I'd present the following examples.
Here is an example of how ferris wheels work. One will note that it is bolted to the ground and spins in a sort of vertical fashion. This video is particularly interesting because the ferris wheel runs on man power - some guys climb up to the top and then shift their weight around, and that's what sets the wheel in motion.
And here is an example of a carousel. One will note that unlike the ferris wheel, the carousel spins in a sort of horizontal fashion. Having the carousel spin in a vertical fashion like the ferris wheel would be a BAD THING.
I hope that clears everything up.
(Yeah, I know, Kevin is never going to read this. Nor will Ron Jeremy, for that matter.)
