A flare is a type of pyrotechnic[?] that produces a long-duration brilliant light without an explosion. Flares are sometimes launched into the air with a rocket and then suspended from a small parachute to slow its descent, providing a temporary source of light for a large area of land. They are sometimes lit on the ground to use as a signal. Flares generally produce their light through the combustion of magnesium metal, sometimes colored by the inclusion of other metals.
