In 1950, the Gilbert Company put out this Atomic Energy Lab. “The kit’s intention was to allow children to create and watch nuclear and chemical reactions using radioactive material.” I love that the model number is U-238.
Exciting! Safe! What could be more wholesome than experimenting with nuclear physics? “Decades later, the lab set was criticized as ‘the world’s most dangerous toy’ because of the radioactive material it included.” Oh.
Still love it. Photo by Renaissance Restorations
