Murmelbahn like a Pinball: Blue Marble 3

Murmelentusiast Kaplamino hat die letzten Monate damit verbracht seine neue Murmel-Kettenreaktionsmaschine zu bauen und vielleicht ist das die beste von allen, die er bisher zusammengebastelt hat. Hat teilweise sogar was von einem Flipperautomaten. Großer Murmelsport!

I didn’t post for two months, now you know why ! I present you my most ambitious project so far, blue marble 3 ! I’m out of my comfort zone this time because the chain reaction is taking place on two tables, and with 0 fidget spinners. It is the longest in terms of duration and the one that takes up the most space in my room. I tried to use a little bit of everything like rubber bands, magnets, and elements. I had so many failures that I stopped counting, as always only a few tricks were responsible for the majority of failures, can you guess which ones?

Kleine blaue Murmel als Anstoß zu Allem: Blue marble 2

Ich liebe diesen Shice wirklich sehr: Kaplamino hat nach seinem „Blue Marble“-Video zu Beginn diesen Jahres jetzt nachgelegt und „Blue Marble 2“ gebaut. Nicht weniger aufwendig, nicht weniger geil. Großartig! Mindestens.

„The trick at 0:23 caused the majority of the fails. It had to be exactly in the right position and it was moving because of the vibrations of the trick above. The air canon with the balloon was a big challenge to make. The rubber band squeezes the balloon around the straw to release the air in a specific direction. Then the hardest part was to find how to stop the air and deliver it when I want. It was too difficult to put something like tape at the end of the straw because it was either too clingy or not enough. The solution was to twist the balloon around the straw and block it in this position with a rope. In this position the air stays in the balloon until it untwists. I explain it because I think what exactly happened it’s not easy to get when you see the video. After this I built a timing catapult trick. I know I’m crazy because timing tricks are so unreliable, it was mostly based on luck but worked 80% of the time. It was so sensitive, just a little more dust or some hair on my table could make it fail so I had to clean it for almost every take. Yep I used a fidget spinner again, I’m proud of this one, nice and almost never failed. The big catapult was supposed to be a trick with fire (the plan was to build something with elements: fire, air and water). The marble was supposed to go up because of the explosion of a firecracker :p But it was too risky, I know it can work (it worked 2 times) but with MASSIVE luck. It’s impossible to predict how they’ll explode. And it caused lots of others problems. The marble was burned and it wasn’t rolling really well after that. The shockwave can trigger other tricks and finally the debris from the explosions was falling all over the place and could block the marble at a later stage. It also burned the table and hurt my ears. So I gave up, but maybe you’ll find this trick in a screenlink later ;) About the water trick. Release the water was really easy, but it took me weeks to figure out what to do with it. You can’t push something with it, not enough force … So I taped a folded paper and when the water touched it, it got wet and unfold because of the weight :D But the marble also touches the water and gets wet. After that you can see that it moves slowly. So the final trick had to be VERY sensitive. Why do I always put the most sensitive trick at the end?“

The Blue Marble

Wahnsinnig gute Murmelbahn von Kaplamino, der daran drei Monate und hunderte Versuche lang arbeitete.

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.
