      They’re absurdly overpriced, but I wonder how quickly you’d make your money back if you bought a big one and had men pay a fee to mess with it for a few minutes.

          I’m certain that all metals are flammable if you try hard enough, because all it takes is oxidation. Quite a number of them can burn in a self-sustaining manner in terrestrial conditions, though, mostly provided if and only if you manage to have enough surface area of the stuff available in one place. Powdering them usually works for that. Or, if you’d like to watch some iron burn, a fun science fact is that you can light a wad of regular old steel wool like the kind you’d buy at the grocery store as if it were a cotton ball. The finer sized the better, and you should probably also do this outside.

            My admittedly not great understanding of it was along the lines of some metals are too good at conducting heat and would basically put their own fires out in most circumstances. I do not know if that is correct

              Maybe, but I can tell you that copper’s thermal conductivity is better than e.g. gold, and copper can absolutely burn in open air if the particle sizes are small enough. Aluminum will too, of course.

              I’m not about to try it with my meager supply of gold. The stuff is damned expensive at the moment.

    • William Osman made the tungsten cube so expensive. It was like $2k when he did his video wrecking shit with it. Now they’re asking $10k for the 3 inch cube.

      I respect the hustle, but damn.

      Still, the 1 cm model is like $50 and would still be absurdly heavy for its size, even if it only weighs 19¼ grams.

      Might be worth it to find yourself a bunch of old incandescent lightbulbs and get the filaments out instead.
