The lab I worked in had some leftover liquid helium so we froze some LEDs and laser diodes!! This vid is from my 2015 (and my commentary is pretty annoying lol) but the content is pretty cool. It's not every day you get to interact with something so unbelievably cold.

Dunking some LEDs and laser diodes in liquid helium!! Liquid helium boils at just 4 degrees above absolute zero at standard pressure.
