The appearance of the glass tube in the sand from lightning due to the fact that between the grains are always in the air and moisture. Electric lightning current heats for fractions of a second air and water vapor to huge temperature, causing explosive air pressure between the grains and increase its extension.

The expanding air forms a cylindrical cavity within the molten sand, and subsequent rapid cooling fixes fulgurite - sand in a glass tube. Often carefully dug out of the sand fulgurite the shape of a root of the tree or branch with numerous branches.
