When Water Levitates

Subscribe! http://bit.ly/ACSReactions

Have you ever seen a drop of water navigate a maze? It’s possible thanks to a weird phenomenon called 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 work out how super hot water behaves on metal surfaces. These little levitating water droplets are a big deal — this could also help prevent future nuclear disasters.
