So, one of the cars pushes a lever, which activates the machine. The cars continue racing down the track as a silver marble passes them and pushes a domino that causes a domino effect. Eventually, the last domino pushes a group of marbles down a track. All of them, except for the red one, fall off the track, while the red marble pushes a lever that causes a water tower to pour water into a plastic tub. A few seconds later, the cars fall into the water. The red marble returns to activate a lift that lifts the cars out of the tub and allows them to continue on the track.
Now, I could probably create that kind of track, but I would need help from a grownup, because if something made out of glass that is required for that track breaks, it could lead to some serious trouble. I can explain how the rube goldberg machine works if you want me to.
Boi, you are reading my mind. I had those too. The color-changing effect is super cool. Imagine if you had a race track, and two Hot Wheels were racing against each other. One of the cars activates a rube goldberg machine that causes water to spill out onto both cars, but only one of them changes color. I almost did that kind of track, but I didn't have the parts needed for such a track.
