The Blue Marble, an uninterrupted catapult-filled magnet marble run

After 3 months of work and probably more than 500 fails, I’m happy to present you my best video ever. Since magnets and marbles I’ve always wanted to make a big chain reaction in one take with this 2D style!

It’s also a “one marble path” which means you have to follow the same marble for all the tricks (in that case the little blue one.) Because everything is in a tilted plane, the hard part was to find different ways of having the marble riding up along the table (magnets, falling weight, catapult …). To do that, the marble has to be light. And because everything has to be triggered by this little marble, all the tricks are very unstable. Most fails happened when an element fall down earlier than expected.

This creative and complex magnet and catapult-filled marble run by chain reaction YouTuber Kaplamino is a wonder to watch. Serious DIY-inspiration for any Rube Goldberg enthusiast: The Blue Marble.
