If conditions are right, the fused sand forms long hollow tubes called fulgurite. The term comes from the Latin word fulgur, which means lightning. Although lightning strikes earth at least a million times each day, only rarely does fulgurites form. Fulgurites are usually found beneath the surface of the sand, generally decreasing in diameter and sometimes branching outs as they descend.
Last month, taking advantage of a lightning visit to Australia to spend a few days with the castaway David Glasheen, I was lucky to visit this beach of Jervis Bay, not only to analyse the sand to find out the composition of these tiny grains but see for myself the true colour of the sand and to compare it with that on our desert islands.
