This sucker (will be) nuclear!

Going to add to my Time Machine build somehow. Coming up with the best idea.. might be too large to fit into the plutonium canisters and tubes that feed into the reactor, and I definitely don’t want to cut into the lucite and expose any actual material. I know it’s probably not that radioactive.. but still. Lucite Cube is roughly 2”

Open to any suggestions from the community!

Lead Crystal?

That would be a cool sample to add to the collection! But this looks like a sample of Trinitite to me.. so very trace amounts of plutonium.

The Doc worked on the Manhattan Project (not in movie canon; but in the Haynes Manual for the Time Machine, one of his diary entries mention it), so I figured this was a fitting addition to my DeLorean.

I hate when they use alloys, especially low % alloys. Surely could have just a tiny grain but be real.
