The flare is designed to produce a brilliant light that can be seen for miles, especially on a flat surface such as the sea. Mixing potassium nitrate with charcoal and sulfur and adding certain metals such as aluminum or magnesium produce the bright light of a flare. The metals burn to produce the brilliant light without exploding, making it safer for the person setting the flare. The light of a flare is so intense that it can even burn underwater to mark submerged objects. What is left after the metal is burned is an ash-colored compound that is a combination of the metal and oxygen.

They're usually fired high in the air so they can be seen from much greater distances than handheld flares (up to 40km/25 mile or so in good visibility).]]> 2018-12-12 18:50:24 UTC https://padlet.com/cousisa/3ubz3ffwhx9w/wish/313995128 cousisa https://padlet.com/cousisa/3ubz3ffwhx9w/wish/313998483 Traditional road flares burn out in 15 minutes .

These two ingredients can sustain a candle flame. In the case of an underwater flare, both the combustible substance and the oxidizer must be supplied by hoses leading down to the flare, since no free oxygen is available underwater.]]> 2018-12-12 18:57:42 UTC https://padlet.com/cousisa/3ubz3ffwhx9w/wish/313998832 cousisa https://padlet.com/cousisa/3ubz3ffwhx9w/wish/314000644  191 °C (376 °F) and burn as hot as 1,600 °C (2,900 °F).
