SciShow Tangents is the lightly competitive knowledge showcase from the geniuses behind the YouTube series SciShow. Every other Tuesday, join Hank Green, Ceri Riley, and Sam Schultz as they try to one-up and amaze each other with weird and funny scientific research... while not getting distracted. There will be tangents about video games, music, weird smells, surprisingly deep insights about life, and of course, poop, but it always comes back to the science.

episode 27: Hair
Mammals pretty much have the market cornered on hair, and you know all the other types of animals are jealous of us. Imagine a little lizard with bangs or something? It just wouldn’t be right. Sorry!
