YOUCHEMISTRY: Lightbulb in liquid nitrogen

Lightbulb in liquid nitrogen

from TheBlueginjava



A bare wolfram lightbulb filament in a beaker of liquid nitrogen can be connected to an electric current safely and without decomposition of the filament, shining as a normal lightbulb. The liquid nitrogen is a non conductive and almost inert material that isolates the wolfram filament from the atmospheric oxygen that would burn it out. The video explains it very well!!
