Day six: Cosmologists for the 21st Century "I had a great experience, and learned more than I ever thought possible in one week. I was amazed at the caliber of the minds that lectured us each and every day. I will certainly use what I have learned for the rest of my life." David E, student |

After students and teachers were presented with merit certificates, Dr. Otto made ice cream with liquid nitrogen for the group
Liquid nitrogen is produced industrially in large quantities by fractional distillation of liquid air and is often referred to by the abbreviation, LN2. It is pure nitrogen, in a liquid state. Liquid nitrogen boils at 77 K (−196 °C/−321 °F), and is a cryogenic fluid. Despite its reputation, liquid nitrogen's efficiency as a coolant is reduced by the fact that it boils immediately on contact with a warmer object, enveloping the object in insulating nitrogen gas. This effect is known as the Leidenfrost effect and applies to any liquid in contact with an object significantly hotter than its boiling point. More rapid cooling may be obtained by plunging an object into a slush of liquid and solid nitrogen than into liquid nitrogen alone.
