Lightning can occur in a short time, which can expend energy by 5 gigajoules, whose strength enough to flatten a house. However, it is now lightning can be 'caught' even leaving a trail of fossilized lightning.
Could we catch lightning? The answer is certainly not, and it could become impossible to use. But what about other objects, such as sand, soil, or electronic tools are used?
Maybe it will sound strange, if it turns out there are things that it can 'catch' lightning. Lightning itself is an electric current that occur due to friction that can occur between the cloud with the cloud, or cloud to the mainland.

When a powerful lightning hit the sandy areas like the beach or dunes, sand particles can melt and dry out together in less than one second. Sand melts at about 1800 degrees Celsius, but the temperature of a bolt of lighting can reach 30,000 degrees, or more than five times the temperature at the surface of the sun.
If conditions are right, the sand fused and formed a long hollow tube called fulgurite. The term comes from the Latin word fulgur, which means "lightning". Although the lightning strike into the earth at least one million times each day, rarely forming fulgurites.
Fulgurites usually found below the sand surface, generally branched with varying diameters. The form reflects the path of lightning, which hit into the ground. Therefore, fulgurites sometimes called "fossil lightning".
Fulgurites look like root, branched, and has a rough surface, covered with sand grains are partially melted. But the inner surface is usually smooth as glass due to rapid cooling and solidification of sand. Fulgurite size and length depending on the strength of a lightning strike and thickness of the sand.
Many fulgurites were found to have only one or two inches in diameter and can reach 30 inches long, but fulgurites with a length of 4.8 meters was found. Some fulgurites can penetrate deep into the soil.
Fulgurites also can be formed when lightning strikes the stone, glass and form a crust and sometimes as veins on the surface layer of rock that had been there previously.
Fulgurites have been found since the beginning of 1711 and are found worldwide, from the mountaintop to the Sahara desert, but is considered rare. They are worthless but appreciated by many for their scientific value. By studying the distribution fulgurites in certain areas, for example, one can infer the occurrence of hurricane activity in the area during a certain period, which in turn can help to understand the past climate.
Fulgurites oldest discovered 250 million-year-old found in the Sahara, which proves if the desert was once a fertile area, where rainstorms ever hit the area.
