The Gilbert Atomic Energy Lab
The Gilbert Company was all about making toys and kits for children to become supervillains when they got older … at least that's our theory. Their Atomic Energy Lab was exactly what the name implies. The kit came with a Uranium-238 Geiger counter, a Wilson cloud chamber, a spinthariscope, electroscope, and four samples of uranium ores. Yes, you read that correctly: the kids got a hold of uranium-238, which is radioactive. And though it's not fissile by itself, it is used to make plutonium-239 (the main ingredient used in atomic weapons). Of course, kids weren't putting together little Manhattan Projects in their garages with these samples. No, they were getting cancer.
U-238 has been linked to everything from leukemia to lymphoma and Gulf War Syndrome. It's not something that should be handled lightly and it should never be put into the hands of children who just want to learn about atomic energy.
This set was released back in 1950, five full years after the only two atomic bombs were ever detonated during warfare. You would think Gilbert might have looked up the dangers of the stuff. The kit was pretty expensive. It cost around $350 in today's money, so few people bought it for their eager young supervillains, and it was discontinued after only two years.

I take exception to the characterization ..... there is no Uranium-238, but Uranium bearing ores autunite, torbernite, uraninite, and carnotite
