Isn't there supposed to be some kind of phenomenum that occurs during particularly intense lightning storms called ball lightning? I just wondered because when I was growing up in China we were told stories about these things that were supposed to follow people around (which no doubt scarred me for life ). For a long time I thought this was just some made up story until I recently read a newspaper article describing a similar ocurrance - is it real, does anyone know how it happens?

(Yeay! It snowed in London today and set!! )
