The “Disease” That Struck Medieval Church Organs
SciShow is supported by Brilliant.org. Go to https://Brilliant.org/SciShow to get 20% off of an annual Premium subscription. During long, cold winters in medieval Europe, church organs grew gray, sickly-looking circles that spread over their pipes. People back then believed that this was the work of the devil, but as it turns out, it’s just some pretty simple chemistry. Hosted by: Stefan Chin SciShow has a spinoff podcast! It's called SciShow Tangents. Check it out at http://www.scishowtangents.org
