Fossilised Lightning - Who Knew?

Fulgurite is the name for fossilized lightning. They are natural hollow glass tubes formed in quartzose sand, or silica, or soil by lightning strikes and are formed when lightning with a temperature of at least 1,800 degrees Celsius instantaneously melts silica on a conductive surface and fuses grains together. The image above is a fulgurite.
