Fact of the Day: Far Away Thunder

Since thunder moves at the speed of sound, you always see lightning before you hear thunder. To determine the distance of where it landed, you count the seconds until you hear the thunder. You divide the seconds by five and that's how many miles away it was. For example, if you counted 10 seconds, then the lightning was two miles away.

As long as it stays far away. Unless it wants to hit me and give me super powers.

Oh, I always thought the seconds you counted were the miles. Glad to know that. Gosh, that means the storms were closer that I thought. :) I am afraid of lightning!
