However hot this summer gets, it won't beat what you're about to see.

Some 230 years ago, three London gentlemen walked into a room with a few eggs, a steak and a dog, and then cranked up the heat. Their goal? To find out how much heat a body could stand. The fabulous animator Lev Yilmaz, author of the comic series Tales of Mere Existence, takes the story from here:

If Lev's story has you curious, check out our radio version of this experiment. Biologist Bernd Heinrich, author of Summer World, takes us deeper into the science of how sweat kept these men from collapsing at a temperature higher than the boiling point of water. (P.S. The dog was fine, too.)
