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.

But uranium is 'eavier.

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.

thyrell is dead :(

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.

I don’t get it
