Can a Magnesium fire be put out?

The video explores the properties of magnesium, particularly its use as a fire starter. The host conducts experiments to ignite a whole block of magnesium, demonstrating its intense brightness and heat. Attempts to extinguish the fire using dry ice are shown to be ineffective, as magnesium can extract oxygen from carbon dioxide. The host then sources magnesium from car parts for further experiments. Spraying water on a magnesium fire is tested, resulting in a dramatic explosion. The video concludes with a demonstration of magnesium's brightness, lighting up the entire backyard.
