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.

You need to clean a smudge of your glasses? Use some spit! Gotta make some food moist so you can swallow it? Why not try spit? Lips too dry to whistle a tune? My friend, spit is the bodily excretion for you! Spit: don't leave home without it!
