Marble Tsunami marble run machine: 11,000 marbles

It’s a Marble Tsunami! This huge marble run machine or knikkerbaan has more than 11,000 marbles rolling, sliding, zigzagging, hitting bells, and clacking endlessly into each other, making quite a cacophony. With four paths and four tipping containers, the Marble Tsunami debuted in June 2015 at Monkey Town Indoor Playground in Gouda, The Netherlands.

DIY: With cardboard rolls, egg cartons, craft sticks, stiff paper, tape, and Rube Goldberg-style persistence, you can build a homemade marble run.

We’re also fans of Hape’s wooden marble run sets, a TKSST Gift Guide recommendation.
