SciShow Tangents
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.

To that I say: simply try not to think about it too hard!SciShow Tangents is on YouTube! Go to www.youtube.com/scishowtangents to check out this episode with the added bonus of seeing our faces!
