Sci-Fi Marble Run Lab

This is the Sci-Fi Lab B7, a kinetic sculpture where engineering meets imagination. This laboratory structure features a motor-driven marble system powered by a N20 motor (400 RPM recommended), which drives 4 synchronized conveyor belts lifting 8 mm steel marbles to the top. From there, the marbles descend through a network of spiraling rails winding around the lab’s core.At the Front, a glowing blue lab tube radiates energy, while 14 interlocking gears transmit motion throughout the mechanism, creating a smooth flow. Building the B7 is a complex but deeply satisfying project — a mix of precision mechanics and sci-fi design that results in a functional marble run and a striking display piece.
