I have one of the original screen used Plutonium Canister used in the beloved film Back to the Future. I bought this from the 2015 Prop Store auction 4 years ago. I’m sure many Back to the Future fans from this site have already seen this on the Prop Store website. But I wanted to post this prop Incase if anyone needs more photos and references for making a prop replica plutonium canister for their own collection or DeLorean. This prop was once filled with water and the contents have since been drained, the core is secured by two plastic washers that are no longer stationary inside the container as the rod had to drop into the reactor of the DeLorean on screen. It shows minor wear due to production use and age. Dimensions: 8 cm x 8 cm x 18 cm (3” x 3” x 7 1/4”) if anyone from this site needs more information or photos of the prop let me know!
