Can a Magnesium fire be put out?4m50s

Can a Magnesium fire be put out?

Magnesium is a pretty cool thing. It's the ninth most abundant element in the universe and fourth most commmon on our planet. The coolest thing about magnesium is that it can be used as an emergency fire starter because it has a low melting point. A magnesium fire burns bright and it's virtually inextinguishable, so don't try this next experiment at home! Chemistry is a fun subject, but you need to take a lot of precausions. The Backyard Scientist will take that burden off your shoulders by showing you how magnesium ignites, how bright magnesium fire is and how to extinguish it. He tries covering the fire with dry ice, which is basically frozen CO2, but the fire takes it's sweet time to go out, since magnesium fire draws the oxygen from the CO2. Don't try to put it out with water either! It will cause an explosion that looks really cool in slo-mo, but it may cause additional damage. The best way to put out a magnesium fire is to cover it in sand, in order to smother the fire by removing it's O2 source! Are you a science junkie? Share this video with your friends to educate them on the effects and dangers of a magnesium fire.
