A few months ago I bought a dry ice maker, which was pretty much just a denim sock, strapped to a CO2 tank. I really wanted a nice block of it though, so I bought a different tool thing to make it. It looks a lot more complicated than a fancy sock, but it also doesn’t seem too crazy. I quickly skimmed the instructions, and the only warning, was to keep the pressure really low, so I guess I’ll just go ahead and try it out.
