In our latest episode, we take on a common breakfast disturbance - the foul taste of orange juice after you brush your teeth. Toothpaste is loaded with a cornucopia of chemicals that add flavors, body, texture, and most importantly, the ability to clean your teeth. One compound in particular, a detergent known as sodium lauryl sulfate is responsible for the suds that you produce when brushing. As it turns out, this compound has an interesting effect on your mouths taste receptors. Watch the video to find out exactly how SLS affects your sense of taste, and be prepared to amaze your friends at breakfast when you drop chemical facts on why this bitter combo leads to such a puckered up, gross experience.

To kick off our new series of Bytesize demo videos, we went to the guy who literally wrote the book on chemistry demos: University of Wisconsin-Madison Chemistry Professor and 2012 ACS President Bassam Shakhashiri, author of the popular “Chemical Demonstrations” textbooks. Check out the first Bytesize Demo to see a stunning “chemical oscillating reaction” that changes from a beautiful amber color to a very dark blue and back again (and again and again).

Is that "priceless" painting the real deal or a cheap fake? How chemists use CSI tools to find out

When it comes to detecting art forgery, the stakes are high. Paintings and sculptures carry price tags of tens or hundreds of millions of dollars. A chemical analysis can validate the price, or trash it. In this episode of ChemMatters, find out about the scientific techniques, many based on chemistry, used to examine paintings at the molecular level and determine whether they are fakes or the “real deal.”
