HOLLOW GLASS TUBE.
 |
| FULGURITE |
When lightning hits on quartzose sand, it leads to the formation of natural hollow glass tubes. The quartzose sand mainly contains silica. As lightning hits on sand, the temperature raises to 3270 degree Fahrenheit which results in the instantaneous melting of silica content in the soil on a conductive surface and fuses grains together. The cooled product thus formed is Fulgurite. The process occurs in a time gap of one second. The huge amount of electric charge from lightning is the main reason behind the formation of hollow glass tubes. The glass thus formed is called Lechatelierite. These glass tubes can also be formed by a heavy meteorite impact or a volcanic eruption.
Like this phenomena, these glass tubes can be formed when a high electric current cable break into a conductive surface with sand beneath.
However the tubes formed are different in its length and diameter. The biggest tube is formed in north Florida USA which had 4.9 meters as its length. Their color and nature depends upon the composition and mixture of sand.
