A Rube Goldberg machine

From Matthew, who says, “It’s not a really an RG machine but it is smart and has >1 m views in a week…”  This is a really cool contraption, and uses just ordinary household stuff, along with springs and magnets. I can only imagine the work it took to make this!

And the video’s notes:

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 !

    How in the world did he think of those mechanisms? The human brain is an awesome blob of tissue!

    Thank you, thank you for this lovely piece of super-intricate fun! I appreciate creativity like this! Now I’m going to share it with a bunch of people.

    Waste of time?
    Or time of his life?

    Mesmerizing with smiles. I didn’t want it to end.

    I especially like how it frequently has one or two mechanisms activate in order to then get the little marble to continue on its way.

    That’s awesome!

    I could watch it all day, it’s almost hypnotizing!

    Pretty freakin’ kool. Like the way he changes speeds, like a cagey starting pitcher.

    Very impressive! I think Matthew may have watched this video a few times:

    Very nice!

    Loved the way the marble was several times sent back through the same path but with enough different momentum or something that it came out differently. Wonderful!

    Anyone else remember Sierra’s computer game, The Incredible Machine?

    Why?

      They had no choice once they decided to. They had no choice about deciding to. Their inner marbles propelled them to the decision.

    Neat! It’s a mechanical engineering thesis project that had to take months to perfect.
