This short excerpt from our Magellan-Elcano world circumnavigation video discusses a commonly observed natural phenomenon called St. Elmo’s Fire, that has been recorded by sailors since ancient times. It relates to the build up of an electrical charge around the tops of masts during storms, in which a bluish purple glow – called a coronal discharge is emitted from the object, much as popular plasma balls do today.
