    Since its critical mass is 52kg, a 100kg of uranium-235 would make a mushroom cloud the moment you put it all in one bag.

      I like where your head is at, but that’s not how criticality works.

      It’d definitely be deadly, but wouldn’t mushroom cloud.

        This. The Demon Core experiments did not cause full on explosions. Just massive lethal doses of radiation.

        Good point. Just read more about it and it seems to require certain conditions to trigger a fission reaction the way I described it. E.g temperature, pressure, shape of the payload.

        Still, while these variables are uncertain, I wouldn’t rule it out.

    But what volume would it be? Is it a small amount of glitter or a lot? What’s the g/cm³ of glitter? What about tiny bits of uranium? I feel like all the little bits of air between the glitter particles would lower the density compared with just a solid block of uranium which would increase the volume but…

    I feel like someone should put some numbers in this thread.

      I could but I’m too tired. Here is a picture of bulk glitter instead. Good luck finding listings for kilograms of uranium.

      Obligatory mention: industry leader Glitterex has a customer that buys significantly more than anyone else, and they refuse to spill the beans. Internet folk have been searching for the answer for years with little luck. If you live in the Jersey City metro area and have torture equipment, you might solve a great conspiracy theory. /s

    We’re they thinking that you’d have to alter the shape/size of individual glitter (glits?) to account for the density of uranium? Is that even a thing you’d need to do?

    I mean, it doesn’t weigh 100 kg. That’s a measurement of mass, not weight. We often discuss our weight using kilograms with the assumption that we’re talking about it at sea level, but the weight would be different at different altitudes. It may be pretty negligible though, I suppose.
