Mr. Freeze Visits Hester!

Last Friday we were fortunate enough to have "Mr. Freeze of Fermilab" visit the 6th grade students and give them a demonstration of cryogenics.  Cryogenics is the science of how you make things really cold and what happens when you do that!! (The production of very low temperatures (below 150 °C, 238 °F or 123 K) and the behavior of materials at those temperatures.)  Students weren't the only ones learning - I learned lots of new information too!  Students were actively engaged from start to finish and even had the opportunity to taste a frozen marshmallow too.

Here's some pictures from the show:
