Using A Vacuum Chamber To Freeze Nitrogen Into A Solid

This is a video of The Action Lab’s James Orgill using a vacuum chamber to increase a cup of liquid nitrogen’s evaporation (as a result of increased boiling due to the lower pressure), causing the temperature to drop until it freezes into a solid around 66 degrees above absolute zero (-341°F, -207°C). Now that’s cold! As cold as a witch’s nipples? *unconsciously rubbing matching frostbite scars on cheeks* Now let’s not get ahead of ourselves.
