The best chain-reaction Rube Goldberg machine I've seen yet

Kaplamino's "The Blue Marble" is made from ordinary items like rubber bands, magnets, blocks of wood, pencils, bottle caps, and plastic forks, but he turns it into an almost magical chain reaction machine on a tilted wood plane.

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.

I learned a lot about chain reaction, and I discovered the amazing power of the hot glue gun!
