Ben Franklin flew his kite in a rainstorm on this day in 1752, and discovered electricity when the kite was struck by lightning. Today, he wouldn't need a rainstorm. If he flew his kite in many American backyards, he?d get the shock of his life if it touched the high-voltage power lines overhead. In fact, he wouldn't need a kite at all to encounter electricity. All he'd need to do is climb a tree near these lines or dig a hole where a cable is buried. In Franklin's day, everything was clear and open, and he had to go looking for electricity. Today, high-voltage danger lurks all around us -- overhead, underground and in stormy skies. Think "safety" when using metal ladders and trimming trees. Electricity passes right through metal tools and even can travel through dry soil -- to shock you. This summer as you spend more time outdoors gardening, painting and flying kites, remember old Ben, and have a safe summer. And that's the On The House tip for today.
