What is Fulgurite?

A fulgurite is a hollow tube of natural glass created in a split second when lightning strikes sand or soil, melting it at temperatures of thousands of degrees. The outside is rough with fused sand grains, while the inside can be glassy and smooth. Fulgurites are found in desert dunes such as the Sahara and on beaches.
