They have been known to occur on beaches, deserts, and mountains around the world, but what exactly are these weirdly brilliant looking sand structures and what causes them to occur?
They are called Fulgurites, and if you ever find one, you may not want to touch it, because these sand structures can be extremely fragile.
Usually caused by lightning strikes, the sand becomes crystallized from being hit by the high-temperatures. Sand melts at around 1700°C and the difference in structure depends on the size and shape of the lightning bolt.
They can measure from a few inches to several feet in length. Fulgurites can be rare, and ultimately fragile so it’s probably best to simply leave them alone and admire them from afar if you see them.
