This week, the Other Couch's high-school-level understanding of chemistry is really put to the test as we talk about acid! What is it? How does it dissolve things? It has something to do... with protons? It seems way simpler in the movies!

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