Winters in Brooklyn are cold, but Midwood Science students know a much colder cold — liquid nitrogen. Nitrogen is the primary component of air. In its liquid phase it boils at −196 °C, just 77 degrees above absolute zero (77 kelvin). It’s hard to find anything colder than that. Pour it on the floor and it’s cold enough to make micro-clouds. Midwood Science seniors traditionally celebrate the end of the fall semester with 30 second liquid nitrogen ice cream and other cryogenic experiments like the one shown below. Because science is just that awesome.
