What is Lightening?

I was reading the boys a book tonight about Thunder and Lightening. The question came up..."What is lightening?" So I asked them.

Here are there responses:

Sawyer : "CRACK"
MY HEAD WAS THINKING: "Well, some people on Crack might feel like that... not sure!"
WHAT I SAID: "Chuckle", I guess it could make a cracking noise."
Sawyer: "Fire, mommy, Fire"
WHAT I SAID: "Good job honey, it is a lot like fire in the sky."
Braxton: "Race Car"
WHAT I SAID: "I didn't even think of that Braxton, Lightening McQueen is a race car!"
WHAT I WAS THINKING: "Man, adults have such a one track mind, how neat it is to hear what the kids really think something is!!!"
