We originally featured Reactions in the Scout Report on 3-10-2017. Since then, this excellent channel has been joined by PBS Digital Studios and has added dozens of educational and entertaining videos. What is catnip, and why do cats react to it? What is the best way to clean and care for a cast iron skillet? How does Xanax work? Why do onions make you cry? From the American Chemical Society (ACS) comes Reactions, a series of videos that address the kind of chemistry questions that you've probably found yourself pondering about at some point. Each video is approximately three to five minutes in length and presents a series of engaging video clips and diagrams. Through these videos, viewers will learn about an array of chemical compounds that affect their everyday lives, perhaps in a way they did not realize. These videos make for enjoyable browsing for the generally curious and provide some helpful life hacks to boot.
