Testtttiiiiinnnng

Today I learned that liquid nitrogen is not to be trifled with. In fairness, I already knew this (so many training sessions), but nothing hits it home like frantically trying to turn a stopcock whilst wearing oversized comedy yellow cryogloves, because a frothing -80 degree liquid is spilling out of your metal container and freezing the kerb wildlife, and threatening to asphyxiate you with clouds of nitrogenous smoke.

Hehe. Stopcock.
