Will o' the Wisp
A will o' the wisp is a ghostly, pale light sometimes seen at night hovering and sliding around in swamps and graveyards. Will o' the wisps recede if approached, and are traditionally held to be mischievous spirits of the dead or other supernatural beings attempting to lead travellers astray. Scientists believe the will o' the wisp phenomenon is a result of the oxidation of hydrogen phosphide and methane gases produced by the decay of organic material.
It has been pointed out by certain authorities that the standard explanation of marsh gas is unsatisfactory in many cases, particularly in cases where the motions exhibited by the phenomenon are dynamic - bobbing, swooping, soaring upwards and downwards, or even against the wind, in some reports.
William Corliss writes, in Remarkable Luminous Phenomena in Nature (Sourcebook Project, Glen Arm, MD, 2001:290): "No satisfactory mechanism has been demonstrated whereby gases escaping from marshy areas will spontaneously ignite. Furthermore, most low-level nocturnal lights are cold--not what one would expect from burning methane. Also, no one has explained how clouds of luminous gas can maintain size and shape while engaging in erratic maneuvers over many minutes."
Willo the Wisp was a 1983 animated series for children shown by the BBC and featuring the voice of Kenneth Williams.
