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.

episode 25: Holes


Humans have been digging deep holes for fun and profit since time began, and some animals have been doing it for way longer than that! And all of those holes can't hold a candle to some of the natural holes the Earth's got going on. And those are nothing compared to space, which some (Sam) would argue is the biggest hole of all!

Follow us on Twitter @SciShowTangents, where we’ll tweet out topics for upcoming episodes and you can ask the science couch questions!
