Tomorrow at 10:00 AM CST: In this special #DeSTEMber hangout, we take a look at - quite literally - one of the "coolest" parts of CERN.

In the CERN cryogenics laboratory, experts work with liquid nitrogen and liquid helium to cool CERN equipment to temperatures as low as -271°C (about -456°F or 2.15 Kelvin). This temperature is even colder than outer space!

In this special #DeSTEMber hangout, we take a look at - quite literally - one of the "coolest" parts of CERN.

In the CERN cryogenics laboratory, experts work with liquid nitrogen and liquid helium to cool CERN equipment to temperatures as low as -271°C (about -456°F or 2.15 Kelvin). This temperature is even colder than outer space!

In this hangout, our experts perform hands-on experiments to show the weird and wonderful world of liquid nitrogen, and explain why we need to keep parts of CERN so cold.

This is the last hangout of this series before we pause for the winter holidays. To view previous hangouts see: http://www.youtube.com/playlist?list=PLAk-9e5KQYEroNUYrWHAANKJL3LDz9-L
