OK, realistically (in relation to what OP is asking), what stops some father from teaching their 3yo kid how to do advanced shit such as algebra or calculus? In order to make it less boring perhaps you can make symbols out of paper (or carve them out wood) and just show them the rules how to manipulate the symbols. Or you could make an app to with and it throws confetti and shit when they solve an equation to make it fun. They won't understand what they're doing but later in life when they see these equations again they will, and it will be as natural to them as breathing.

The point of doing is this is when they're adults they will think "Well, solving equations is what I've been doing all my life" which by then is probably going to be true.

The ball would stop at the last magnet, like in the video OP posted. If by some luck you actually got the polarities right, you'd not have enough kinetic energy generated to make the ball travel all the way up to the generator and push through its turbine. Even if you did for the first couple of goes (when you most likely pushed the ball in with your hand), it will still eventually fail.
