In 1951, Children Could Buy A DIY Nuclear Reactor Kit

You don't see toys like this around anymore. Who wants the kid next door to create his own Manhattan project in the backyard? The Atomic Energy Lab set was available from 1951 to 1952 and sold for a whopping $50.

The set came with four types of uranium ore, a beta-alpha source, a pure beta source, a gamma source, a spinthariscope, a cloud chamber, an electroscope, a geiger counter, and a manual.
