SciShow Tangents

By: Complexly
  • Summary

  • 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.

Hilarious nerds, surprisingly educational

This is one of the few podcasts that really works well with the free form conversation. You'll learn a lot from each episode, but the strange conversational detours to things like Minions is fantastic.

Silly, science-y fun!

Across a vast array of topics, this podcast loosely follows a game show pattern. Hank Green, our charming host claims to hand out ‘Hank Bucks’ to the winners as he sees fit, and there are a couple of regularly appearing ’games’, for example; each episode the co-hosts present stories about the topic du jour, and Hank decides which story is cooler, then he presents two lies and a fact about the topic, and his co-hosts have to figure out which one is true. The topics range from the silly, Poop, Butts, etc…to interesting science, Elephants, Radiation, Gas, Pain, Ants.
It’s silly irreverent fun, and it’s all cool facts about science! Seriously, one of the best things in life!
