The day is sunny, the water is warm and all you want to do is relax on a beach  blanket on the sand or by the pool and listen to your favorite radio station on your portable stereo. Enter static! Don't let it ruin a beautiful day. Get a piece (or two) of charcoal and place it on top of the radio. The porous charcoal will attract electromagnetic radio waves and transfer them to the stereo leaving you crystal-clear music for the rest of your afternoon. Be sure to pack charcoal in your beach bag!
