[Captions by Y Translator] In the past, we've done some tests to see what happens if we heat up dry ice in a furnace, with a blowtorch, or even by pouring molten metal onto it. Today, we're going to see what happens if we throw it in our mini Arc furnace, which heats up several thousand degrees hotter than any of those. [Music] YouTuber JuicyFox Hackerzzz wanted to know what would happen if we put dry ice in our mini Arc furnace. Well, JFH, we're not sure what's going to happen because dry ice is exceptionally cold, but our many arc furnace is exceptionally hot. It gets up to several thousand degrees in Fahrenheit or Celsius, and it's easily hot enough to melt glass, rock, or steel. What we're going to try is fairly straightforward. We'll see how the arc interacts with the dry ice. We'll see if it makes it melt or sublimate faster than normal, and we'll see if it's any different with solid pieces of dry ice, or powdered dry ice. To start off, let's see the result with a solid chunk of dry ice. I'm also curious to see how the Arc is going to react with the dry ice directly, not the heat from the arc, but just the arc itself on the dry ice. [Music] All right. My first question was to see how the arc itself interacts with our dry ice. And unfortunately, while this does create a very powerful arc, it doesn't really have the ability to separate very far. I'm pretty sure there's very high amperage, but very low voltage running through this thing, and as a result, it does have a hard time separating out much. All right. I'm going to make the arc, and I'm going to point it down and concentrate it on to that dry ice, and we're going to see if it does anything. It might cause it to sublimate really fast, or maybe that much electricity and heat or cause some other unknown reaction. [Music] Cool things happening. First off, with just the arc concentrated on the dry ice, it did not melt, because dry ice does not like to melt unless you have it under extreme pressure, and this is just normal atmospheric pressure. However, the heat of the arc was causing it to sublimate really quickly. It started dissipating way faster than putting in the furnace or anything like that. It wasn't that quick. It was still just sort of a slow disappearance. But one thing we have learned about dry ice in the past is that what makes it sublimate fastest of all is if it's in physical contact with something putting out a lot of heat, and these carbon rods put out a lot of heat. As we have the arc running, it's heating up whatever's in the furnace, but it's also heating up the rods themselves a lot. You can see that they are glowing orange when I take them apart from each other, even when there's no arc traveling between, they're still blazing orange hot. And when I put the hot rods directly in contact with the dry ice, that is when we started seeing it dissipate quickly. You can see that I've just carved right down into this piece, and that was just by touching it to the rods, which are still hot, and still causing it to sublimate quickly on contact. So by taking the rods, arcing them together, heating them up, and then physically touching them against the dry ice, that's when we start really seeing the dry ice get carved away quickly. That might be the fastest I've ever seen anything carve through dry ice. We're going to do the same thing again, but on this slightly larger block, and I'm just going to start poking holes right down into the surface of the dry ice with our carbon rods. [Music] Those rods turned this dry ice into just swiss cheese, like in no time flat. They just tunnel right through that. Look at that, full of holes. All right, we've got a little metal nut here, and we're just going to melt that right on the dry ice. Molten metal does a pretty good job of carving right through this solid carbon dioxide. Let's give it a chance. [Music] Beautiful. So that was a nut, now it's just a ball or a blob. I don't think I can even call that ball-shaped. Melted down in just a couple of seconds, and then it started carving it's way, this beautiful little hole right down into the dry ice. One more thing that we want to test is to see what happens if we take a bunch of our dry ice, crush it up into a powder, and then put that into the arc furnace. [Music] Oh, boy! [Music] That was pretty cool. It's like arching down inside it. [Music] Well, JuicyFox Hackerzzz, no, we can't quite melt dry ice in the arc furnace. We can get it to sublimate pretty quickly, especially if we take those blazing hot carbon rods, and touch them to the dry ice itself. I also really liked the look of them. We had the powdered dry ice with the rods underneath. That was a really cool underglow. Just all lit up quite a bit. Looked very neat, does not melt, but does do some really cool stuff.
