$20 from Amazon, but you have to keep the internal battery charged up, else it won't work 😂

Looks like it doesn't stop. But it does. How? Conservation of energy says ball can't rise higher than its starting point. Hidden battery operated booster inside toy adds extra kinetic energy to ball so it jumps loop & falls on platform . When battery dies, ball can't jump higher.

Where the recharging plug goes...

Doesn’t work with a transparent casing, how odd :)

And I've thought we need nuclear fusion. Never more, just few balls and we will be fine. ;-)

Perpetual motion machines are generally classified into two types: those that violate energy conservation and those that violate the second law of thermodynamics. Modern physics considers both impossible.

Does this win as a perpetual motion machine?

It's in the rim, clearly the ball is acted on there

Fun with (electro) magnets.

Wow I want all the things there thanks for the tip!
