The thermite reaction makes total sense; similarly to a grease fire, you have a flaming substance; you add the water (steam), and it rapidly spreads out the fuel, giving it much more surface area and hence more fire.

if i remember science class, its to do with the thermal expansion coefficient

@CharlieTheNerd91 3 ай бұрын

@@kevinmorrice It is simple to understand in the case of oil. Oil is lighter than water and floats on top of it, so when you add water to hot burning oil, it goes under the oil, and because the oil is soo hot, the water instantly vaporizes below the oil, spreading it out like an expanding balloon, therefore creating a bigger surface area of the burning oil and hence create a much larger fire.

RE: the SKS. getting the firing pin moving would be a bit of a waste of time, considering the sear would have to drop to release the hammer, youre never going to get enough inertia on a half oz part to strike the primer with sufficient force through vibration alone, the sear resonating might have enough movement to allow the hammer to fall. and thats without commenting on spring loaded vs free floating firing pins which changed depending on who made it and when. With Russian 'banditi' they do love their fully automatic weapons, to the point that a chunk of semi auto SKS rifles get converted by filing the sear contact points and the locking shoulder on the back of the receiver. works reasonably well if done properly, but the issue is doing it properly. most of the 'bubba-ushka' conversions just run away or have out of battery detonations injuring the user. thanks to careless chiselling, angle grinding and inflicting the Dremel on them. or the laziest way I've seen it done. pushing the firing pin forward and gluing it in place to convert it to a magdumping full auto runaway weapon once you release the bolt on a loaded mag. though, not really being designed to be used on auto results in obvious safety issues, but if your weapon is illegal anyway. might as well have fun with it i guess? but with the myth stating they fired their whole magazines one after another. that seems most likely.

@xcoder1122 4 ай бұрын

I go with Jamie's idea. The heat cause the ice to directly become steam and the steam will quickly expand, causing the thermite to be blown apart like dust and that probably has a similar effect to flour being blown into a flame. In case you've never seen the later one: kzfaq.info/get/bejne/isqlrJSrupawXYU.html However, flour is many times less reactive than thermite, the heat development is also much lower and the vapor reaction, which blows the flour into the air, is also much less strong.

@leoarc1061 4 ай бұрын

The dispersion of the thermite probably has an effect but perhaps not as much we think. I think that the ice itself is making most of the explosion. If you place something really hot, with a high thermal mass deep into water, the rapid change in phase (from liquid to gas) will create an explosion, or at the very least a big splash. In this case, we have a substance with a temperature of thousands of degrees falling into water which is in an even lower state. A decent amount of water will have to go from a solid to a gas, in a very short amount of time, in a very confined space. Pressure builds up, thus breaking the ice bricks apart. One thing to remember is that the process described above will likely (I have no proof of it) be compounded by the Leidenfrost effect. The liquid metal will have a "protective layer" which will delay the explosion but increase its energy in the end due to allowing more water to change phase.

@GodlikeIridium 4 ай бұрын

Impossible to say without experiments. I think it's maybe the spred of ice particles and/or water droplets and still reacting thermite and hot liquid iron. The iron carries enough thermal energy to make more steam. Thus spreading more still reacting and thus burning thermite. But yeah, just a guess. People thought for years that in alkali metal and water explosions the forming hydrogen caused it, but no, it's a coulombic explosion (reaction at the surface, but the reaction causing more and more positively charged alkali metal cores to repell each other, creating more surface area to react etc. causing an insanely fast reaction with hydrogen forming and later burning. Easily proven by doing it under water or in an inert gas atmosphere without oxygen to burn the forming hydrogen, there's still an explosion.

thermite needs a LOOT of heat to start, so a spark (even a hot one) will not really do, And given the required heat, the termite would not get to ignite before the clothes melt or burn. And even on a heat-resistant backing I am not sure you could get such a fine layer to ignite, as it might be predominantly oxide rather than thermite :)

That is also where the vast majority of jams happen. Firing a bullet is a very simple mechanism with very little to go wrong. The most complex mechanism in any mutli-shot rifle is the the extraction and reloading process. That requires a lot of different processes to be happening at once with very small margins. It's also why automatic rifles from WW2 and even today have a mechanism to manually cycle when this happens.

For that to become an explosion you would have to get more energy out of burning the hydrogen and oxygen than you used to separate the H20: Over-unity. That would violate one of the basic laws of thermodynamics. And would let you construct a perpetual motion machine. It's a steam explosion.

@sparrowflyaway 4 ай бұрын

I always thought the explosion when thermite meets ice was because they're equal and opposite forces. The ice can't cool the thermite, and the thermite can't melt that much ice, so the forces have nowhere to go but out. I'm certainly no scientist so I could be completely wrong, but that was always my theory about this particular myth.

@ste887 4 ай бұрын

i see it the same as throwing water on a cooking oil fire, steam should cause the thermite to spread, expanding surface area leading to a faster burn, than the usual incremental melting you'd get with just hot solid metal that cant be dispersed as easily as a coarse/fine powder mix can be.
