In this video I have two broken light bulbs that I put in my vacuum chamber to see if they will burn out or not. One of the light bulbs I put with air in the vacuum chamber and the other I suck out the air. This test is because usually incandescent light bulbs are under vacuum and have a some inert gas in them to keep the filament from burning out. So I was guessing that the broken light bulb in the vacuum chamber would last much longer than the one in air.
