After several years and millions of views, the American Chemical Society (ACS), the world’s largest scientific society, is bidding farewell to its popular YouTube series Bytesize Science. But you can’t keep a great chemistry video series down for long. We’re proud to announce Reactions, a new weekly video series about the chemistry all around us.  For more Reactions videos, please check out our Youtube channel at: https://www.youtube.com/user/ACSReactions/featured

Interesting tidbits that are short enough to hold the family&#39;s attention, and informative enough to make the listening time worthwhile.  Thanks for teaching us a thing or two!  

Appealing for all ages

Great content, perfect length, great delivery.

Have you ever seen a drop of water navigate a maze? It’s possible thanks to the same phenomenon that lets you know if a griddle is hot enough for pancake batter. Water droplets that dance and skitter across a hot surface instead of boil away on the spot are experiencing the Leidenfrost effect. Understanding Leidenfrost — first described more than 200 years ago — helped engineers make more efficient steam engines. Today, scientists are using high-speed cameras to better characterize how superhot water behaves on metal surfaces. The investigation might lead to improvements in power generation.

Derby Day is around the corner, and with it comes big hats, horses with funny names, and bourbon. The latest episode of Reactions celebrates the chemical process of distillation that makes bourbon and other whiskey varieties possible. Since water and ethanol, along with tasty flavors, have different boiling points, they can be separated by carefully heating the mash that starts off every whiskey. Each distillery carefully protects their still design, engineered to create their signature liquor. The strongest flavors take aging, but might some innovative whiskey makers find a way to hack maturation time? Special thanks to District Distilling in DC!
