What is Bicycle Day?

April 19th celebrates Bicycle Day? But what is this holiday dedicated to? Find out in this Reactions video!

This week Reactions is celebrating Bicycle day with some psychedelic science. The chemistry behind LSD has an interesting story. Chemist Albert Hofmann first discovered the psychedelic effects of Lysergic Acid Diethylamide, or LSD-25. Today we're talking the chemical history of LSD, so get ready to turn on, tune in, but don't drop out... you might just learn something.

[Correction at 0:09 and 1:13: "Hoffman" should be spelled "Hofmann". We've added a correction (via annotation) -- we really regret missing this. Thanks to oildream for pointing this out.]
