Banned Children’s Toys from Christmases Past
December 4th, 2012 by: Jason Fitzpatrick
What could possibly go wrong giving a child a nuclear science kit that includes highly poisonous materials inside? Everything of course, which is why that particular toy only lasted a single holiday.
Buzzfeed reports on some of the toys of holidays past that were quickly pulled off the shelves. In regard to the nuclear kit pictured here, they write:
Only available from 1951–1952, this science kit for CHILDREN included four types of uranium ore, a Geiger counter, a comic called Dagwood Spits the Atom, and a coupon for ordering MORE radioactive materials. One of the four uranium ores included was Po-210 (Polonium) which, by mass, is 250,000 times more toxic than hydrogen cyanide. “Merry Christmas, Kevin, here’s that giant box of poison you asked for.”
