This super cool physics effect called the Leidenfrost effect has been harnessed and actually used for an invention! It is an unusual phenomenon that allows water droplets to levitate and even climb uphill.   Physicists at the University of Bath have harnessed this quirk of physics to create a thermostat without moving parts.  That’s pretty cool, aside from the cost savings and lowered carbon footprint to make a traditional thermostat.  Maybe it even works better and doesn’t wear out so no need for a trip to Home Depot!

Let’s watch this cool phenomenon in the video on page 2
