Magic smoke is an essential component of many electrical components.
History of magic smoke
Magic smoke was first discovered by Luigi Galvani, after performing his famous frog legs experiment. After discovereing what he called 'animal electricity' with it, he went on catching bigger animals in an attempt to power his until-then unused IPod. At the same time, his assistent Leonardo da Vinci went hungry and attempted to bake Galvani's famous experiment. When Galvani came back, carrying assorted legs stolen from horses, monkeys, dragons, snakes and other animals he saw as potential, he attempted to rescue the frog legs, but alas, the fire already was on too long and the magic smoke had escaped from the by now quite burned frog legs.
Unfortunately, Galvani didn't the implications of what we now know has happenend, and it wasn't until that guy read Galvani's diary, the truth became known.
Electronical components containing magic smoke
The first component which was built around the knowledge of magic smoke was the electrolytic capacitor, which uses the magic smoke chemically bound to ceramic wool in order to keep it contained. However, passing current in the "wrong" direction through the capacitor causes the weak bond between the ceramic wool and the smoke to break. The smoke becomes a gas and expands, breaking the casing of the capacitor with a loud "pop" sound. Thereafter even if the capacitor is reassembled it no longer works.
It is demonstrably proven that a component will continue to perform until the magic smoke is observed to leave, at which point the component perform. In this sense it is similar to the copulatory habits of the male human being.
