If you see lightning and want to know how far away the storm is...
Count the number of seconds between the time you see the lightning and the time you hear the thunder.
Then, just plug that number into the following formula to determine the distance in miles that the storm is away from you.
This quick trick will give you a close approximation.

Ask me...I know. One second I was in the tub, the next I was standing beside it through no effort on my part. Never try to beat the storm!
I was trying to rush a bath before an oncoming storm, thinking I had enough time. Lightening struck many miles away, but the force and electricity traveled through the ground, ultimately reaching our area. The electricity then traveled through our pipes, and the combination of this and sitting in the water bounced me out of the tub with a sizzle. I wasn't burned in any way, but did feel quite a tingle for several moments as I was standing beside the tub, looking at where I had been sitting! It was memorable enough that I never tried it again.
