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.
I did too, but a certain loop piece doesn't cooperate with my Hot Wheels. Speaking of Hot Wheels, if you had the Hot Wheels that could glow in the dark, or have wheels that glow, the effect is awesome. Seeing glowing cars race on glowing tracks is just badass in my opinion.
