🎢 WATCH: Built from over 300 m (1,000 ft) of toy tracks, #Marblopolis sent hundreds of spheres rolling through 30 distinct routes before its dismantling in the #Netherlands.

Jelle Bakker assembled the kinetic setup using #LEGO, #Knex, and classic marble runs to create multi-minute descents packed with loops, funnels, and jumps.
