Ozjay Dual-Track 3D Wooden Marble Run turns into a gear-driven marble run where steel balls climb a lift, split at a junction, pass through an elevated tunnel and spin through a vortex.

Why it is listed here

Two parallel tracks give it more to watch than a single-track marble run. It runs on a hand crank with no batteries or motor, so there is nothing to recharge. Laser-cut birch plywood pieces snap together without glue or tools, according to the listing.

What the build involves

Every gear has to align for the lift to run, so turn the crank after each gear stage to catch binding early. Keep the steel marbles in a small dish while building so they do not roll away. If a marble stalls, check that the track sections meet flush at each joint.
