the tall guy was REALLY happy this morning. He said something about both of us sleeping until 8 clocks! I think it was the first time I've slept that long since I can remember (the tall guy says he KNOWS it's the first time we both got to sleep that long). Maybe it was because it had been raining. The tall guy said he was really proud of me because the rain caused all the loud booms in the sky and I wasn't even afraid. He said a lot of puppies didn't like it when there are booms in the sky.
Well I told him they shouldn't be because all it was is thunder caused by lightning, which is a huge discharge of electricity. When lightning strikes huge amounts of electricity shoots through the air, this causes two things to happen.
1. The electricity hits the air and starts it vibrating, anything vibrating causes a sound.
2. The lightning is also very hot and heats up the air around it. Hot air gets bigger: it expands. As lightning is very hot the air gets bigger very quickly and pushes against the air particles starting another vibration.
These vibrations are what you are hearing when you hear thunder, the rumbling of thunder is caused by the vibration or sound bouncing of the ground and the clouds.
He said that was a very good explanation, but he much prefered to think it was just puppies playing in the sky running into each other! I don't know HOW he ever graduated from college....
