Correct me if im wrong, but i was wondering why the pendulums line up exactly in that formation. What i think is because of the different string lengths, each weight moves a different distance, and because of that, they offset slightly to make those patterns

Cool. I wish you explained more about the gel and the constituents of the gel. What are the properties of each chemical by themselves? Why do they gelatinize when they are mixed together? I feel like a lot of the interesting science was omitted from the video.

it must be just aluminum burning in air, the friction heats up tiny aluminum particles to +1000C and it burns in air, there is no rust mix in aluminum with enough spread to call it thermite reaction. a scientist will try all possibilities before taking a conclusion, dissolve the rust with HCl and dry the ball to have same matt/rough surface without the iron oxide and repeat the experiment.

I dont know if that's actually a thermite reaction. I think it's not. Steel balls hitting each other will heat and compress the air between them, creating a shockwave. It works with clean balls and paper too. In this case, it very well may be simply burning the molten base aluminum in the oxygen in the air, and blowing off a tiny bit of iron oxide. Considering the velocities of air, i would be very surprised if the two had a chance to react with each other. Frankly, it would look about the same since either way oxygen is bonding to molten aluminum. In fact, the air oxygen would be MORE energetic since it doesn't have to rip off of an iron. Prove me wrong. I'd love it if this was actually a thermite reaction. Blowing up thermite doesn't usually make the thermite react.

Recreate this experiment over some clean butchers paper, then sweep the paper with a magnet when done. If you even get one microsphere of iron from it, then it thermited (it's a verb now, sorry)

@@cHAOs9 the other thing that might be happening here is an oxide detonation. If you watch Taofledermaus shoot those big aluminum blocks he has, there's almost always a good flash on the impact. Doesn't seem to matter what the slug is made of, either. So maybe the rust, the impact, and the foil being slightly oxidized (not sure that's possible? Maybe only on one side?) just makes a little blasting cap when you slam it all together.

How many students have smashed digits with a poorly-aimed blow? As for determining if it is actually a thermite reaction, I'd try using a couple lumps of a different oxidized metal, perhaps copper for a nice bright green flash, but the copper may not be hard enough to cause a reaction on impact at reasonable speeds.
