"The temperature of lightning is roughly 50,000°F." Lightning is that cold, really? I thought that Earth lightning was at least 500,000°F; my science teacher said that for something to be considered a "true plasma" (whatever that means), it must be at least 500,000°F, but I might have heard him wrong.
