Word of the Day -- Pele's Hair

Pele's hair is volcanic glass threads or fibers formed when small particles of molten material are thrown into the air and spun out by the wind into long hair-like strands. The diameter of the strands is less than 0.5 millimetres (0.020 in), and they can be as long as 2 metres (6.6 ft). The material is gold or golden-brown, and is commonly found downwind from active vents. Pele's hair is primarily a scientific term used by volcanologists, and is derived from Pele, the Hawaiian goddess of volcanoes.
