plutonium, polonium and uranium are all just a little denser than the densest stuff shown here
cool love using virus and watching it explode
but rock turns to stone after being on pressure so its the rock would be in the 1st ring, then wood would be where Sawd would be because of pressure turning wood into sawd, theres also IRON and BMTL that turns into BRMT after being exposed to salt, and there's QRTZ being where PQRZ because of pressure again and theres alot more
if only there was a way to see the density of solid elements
a similar save used low heat GPMP, ig this works too
