Blue Marble 3 is Kaplamino's latest marble chain reaction video. I like the way that many parts of the track are formed as needed by the energy of rubber bands, deflating balloons, magnets, and even a firecracker.
From the YouTube description:
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?
