Rokr Parallel World Alchemy City 3D Marble Run with LED is a futuristic marble track where an automatic ladder lift keeps marbles looping while seven groups of light boxes flash and shift color.

Why it is listed here

Its USB-C lift module keeps marbles moving without any hand cranking, and Viewing Mode lets you run the ambient light alone. A bonus World Module connects horizontally or vertically with other Rokr Parallel World models, so the track can grow. Its listed material is plastic rather than wood, which sets it apart from the wooden marble runs in this category.

What the build involves

Plan on about 3 hours using the jack-type panel system described in the listing. Keep a USB-C power source near the display spot for the lift module. Use Sport Mode for full function and Viewing Mode when you want soft light without the motion.
