When lightning strikes the ground, it will sometimes fuse the soil into a hollow, glass-lined tube called a ‘Fulgurite’.

Specifically, fulgurite is the result of the quartz sand in the ground fusing together after being charged by lightning. It takes temperatures of 1800 degrees Celsius to turn the sand into fulgurite. Lightning is hot enough to make this happen, but the creation of fulgurite is still very rare.
