SciShow Tangents — Science
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.

Holes Apr 28, 2020

Show notes

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!

Rivers Apr 07, 2020

It's Spring here in the Northern Hemisphere, and the rivers swell with crystal clear snowmelt from tall mountain peaks... and we're all stuck inside and can't really look at it! Dang it! So I guess close your eyes and imagine floating down a beautiful river with your favorite podcast hosts as they drone on and on about bridges and salmon and stuff.

Again, a big thanks for choosing us as the thing to spend your time with! Be well, everyone!

Ducks Mar 31, 2020

Show notes

Ducks! Basically a joke of an animal, if we're being perfectly honest. They make silly noises, they waddle around, they are extremely cute and goofy looking, and they love to swim around in big piles of money!

And look, you might see the title and think 'a duck isn't science.' Well i've learned a thing or two from those eggheads on the science couch and I can definitely say that you are wrong! It turns out, everything is science! Seems like a cop out, but it's true.

Anyway, we sincerely hope everyone out there is doing well and staying safe! Love you guys!

Experiments in Space Mar 17, 2020

Space… it’s big, it’s confusing, and there isn’t any gravity! That’s why we have a dedicated team of people up in the International Space Station running all kinds of experiments to try and figure out just what the heck is even going on up there.

Oceans Feb 25, 2020

Show notes

Oceans: they cover 70% of the planet, but what do we really know about them? Like what’s with all the salt, huh? And just what is the difference between a ‘sea’ and an ocean anyway?! I have questions!

This one has a real doozy of a Stefan poem. I cut out a lot of us interrupting him with raucous laughter!
