Tangents

The day has arrived- this is our very last episode of Tangents ever! So of course, we had to talk about a topic that's near and dear to our hearts forever: Tangents. Ride down memory lane with us and returning original host Stefan Chin as we reminisce, try to remember what we've learned, and still learn new stuff in an episode that's the true encapsulation of everything we love about this show. SciShow Tangents is on YouTube! Go to www.youtube.com/scishowtangents to check out this episode with the added bonus of seeing our faces!
