A hair-raising time at the ScienceTechnologyEngineeringMath expo at COD today!  I think this was the first time they held this and it was really well down with a large turnout.  Information of prairie restoration, tornado watchers, weather balloon launches, 3D printers, snakes and lots more.

Oh, and did I mention that they had Mr. Freeze handing out mini-marshmallows frozen in liquid nitrogen?  Cool watching kids chomp down and vapors come out their mouths (pun intended).
