On Earth, gravity keeps the track in place on your bedroom floor. Your bedroom floor MIKE

Yours personally, don't deny that. It also keeps the cars on the track.

In space, yuo've got nothing keeping the track in place. Newton's third law tells us that when the car turn its wheel to make it move forward, it will also make the track move in the opposite direction.

So you're going to have to tether the track down to your (*your*) ISS bedroom floor/wall/ceiling/whatever, or it'll piss off everywhere and mess up some boffins experiments somewhere.

Also, I think you'll need magnetism to keep the car on the track, otherwise the conservation of forward momentum, when the car hits a bend, without the help of gravity to keep the car on the track, would cause the car to come off the track and float away.

So, you need an ISS bedroom, some bungee to tether the track down, magnets in the car to keep it on a suitably provisioned metal-enriched track, and you're good to go.
