Created in 1951, this kit included a Geiger counter, a miniature cloud chamber, an electroscope, a spinthariscope and, shockingly, four types of radioactive uranium ore. Widely considered one of the most dangerous toys of all time thanks to the inclusion of real radioactive materials, the set now sells for 100 times the original price on auction sites.
In this 1960s game from Hasbro, a spinner determined how many twists a player would give a handle. On any single turn, an arm could unexpectedly release a shaving- or whipped-cream covered “pie” into the contestant’s face, resulting in laughs for the kids and a big mess to clean up for mom and dad.
In the 1970s, city parents who were too lazy to drive to the petting zoo could buy their kids this toy for a true farm experience. Feed Milky water by pumping her tail then pull on her teat for a creamy treat … that you should never, ever ingest. Seriously, you’ll grow extra limbs.
