Lightning-strike victims develop a strange rash
One of the lightning facts most people don’t know is that those who are struck by lightning are often temporarily covered with what’s known as red Lichtenberg figures, which are branching, tree-like patterns created by the passage of high voltage electrical discharges along the skin.

Imagine 15 million volts of electricity hitting a tree branch. The most likely result? The heat travels through the tree, vaporising its sap and creating steam that causes the trunk to explode.
