Some travel in distinctly complex paths. See behaviour for more details. Lifetime Ball lightning generally lasts a few seconds, ie. However, some reports are of lights that may last minutes. Behaviour Some mimic the movements of nearby objects, others hug the land.
Some lights appear to 'investigate' other objects.
There are many collisions reported, and sometimes they can do great damage. The lights may pulsate, break up, reform, decay, explode or any combination of these. Audibility Rarely the lights appear to emit crackling or hissing noises. This is very close to the so called auroral noises which I shall go into later. Smell Close encounters with the lights often report of a burning or sulphurous smell.
