When it’s hard to pour a bag of large marbles into a box, build a giant cardboard marble run that can do it.
In the Rube Goldberg tradition of creating a complex machine for a simple task, Japan-based cardboard crafter DanCreator designed, cut, glued, and assembled a huge multi-level series of tracks over the course of a two-month build.
The video above shares a glimpse of how he assembled the cardboard chutes with precision cuts and hot glue. He then shows off all of the ramps, levers, twists, turns, funnels, and other engineering components as marbles roll through the run.
