Magnesium burns very bright white. In the old days, magnesium could be used as a light source and was used to create the flash for cameras. Now, it is used in some fireworks. It is also used to make incendiary bombs.
Since magnesium is a third lighter than aluminum, it is combined with other metals to make missiles and aircraft.
Magnesium oxide (MgO), also called magnesia, is used in some stomach antacids. Magnesium is also used to make epsom salts, which is used to treat minor skin abrasions.
Magnesium is also used for construction. It is known as one of the lightest metals that can be used for construction.
[edit] Is it dangerous?
Magnesium is flammable, and the bright light it gives off can damage the eyes. Do not eat it, as it would most likely kill you before it made it to your stomach. Never place it in fire, and never throw it into an acid which might cause the release of flammable hydrogen gas. Keep away from children, as well as your mouth, call poison control immediately if swallowed, and keep away from fire or could release a deadly gas!
