A Chemistry Prank From The April 1939 Issue Of Popular Science

We’ve had our share of April Fools here at ZME Science, but we’re not even close to the caliber of this joke from Popular Science, which was published in the 1939 issue.

Just a quick warning though: this is really cool and all, but you shouldn’t try it at home! Mercury and its compounds are toxic and can be corrosive, posing huge risks even at room temperature.
