As I recall the stuff can spontaneously combust in water.

I guess you don't ever want to wash your wheels or drive in rain !!!!

Keep in mind that magnesium is regularly tig welded. So no, its doesn't catch fire easily.

The Flys are cool........but for what guys ask for them, I have to settle for Bogarts

Can you even put one out?

Thermal decomposition of water

Thermal decomposition, also called thermolysis, is defined as a chemical reaction whereby a chemical substance breaks up into at least two chemical substances when heated. At elevated temperatures water molecules split into their atomic components hydrogen and oxygen. For example, at 2200 °C about three percent of all H2O molecules are dissociated into various combinations of hydrogen and oxygen atoms, mostly H, H2, O, O2, and OH. Other reaction products like H2O2 or HO2 remain minor. At the very high temperature of 3000 °C more than half of the water molecules are decomposed, but at ambient temperatures only one molecule in 100 trillion dissociates by the effect of heat.

Flammability of Magnesium

Magnesium is highly flammable, especially when powdered or shaved into thin strips, though it is difficult to ignite in mass or bulk. Flame temperatures of magnesium and magnesium alloys can reach 3,100 °C (3,370 K; 5,610 °F),[9] although flame height above the burning metal is usually less than 300 mm (12 in).[10] Once ignited, such fires are difficult to extinguish, with combustion continuing in nitrogen (forming magnesium nitride), carbon dioxide (forming magnesium oxide and carbon), and water (forming magnesium oxide and hydrogen). This property was used in incendiary weapons during the firebombing of cities in World War II, where the only practical civil defense was to smother a burning flare under dry sand to exclude atmosphere from the combustion.
