Klutz - 019123 | LEGO Chain Reactions 2: Gravity Drop by Editors of Klutz

Build a towering marble maze almost 1.5 feet tall using LEGO® and chipboard parts. Release a set of six wooden balls at the start and watch them navigate through a thrilling course—twisting through ramps, flipping spinners, cascading down funnels, and finally landing in their goal buckets. But it doesn’t end there: recreate, expand, and redesign with mini builds like zip‑lines, grabbers, gravity labyrinths, and more. Alongside the builds, the kit includes fun fact-filled non-fiction content on Rube Goldberg machines, famous physicists, and creative “junk drawer” hacks to inspire custom chain reactions. Physics has never been this hands‑on.
