Making yourself glow in the dark – the Gilbert U-238 Atomic Energy lab
Yes, for the low low price of $50, your budding young Feynman would get a kit containing a Geiger counter, a Wilson cloud chamber, a spinthariscope, three illustrated books (including “Dagwood Splits the Atom”) and three highly radioactive ore samples.
