That crackling sound and clothing items that cling to each other when the dryer is emptied can be attributed to static electricity. How it works is the subject of this episode of Bill Nye's thought-provoking series, Bill Nye the Science Guy: Static Electricity. Once again, the Science Guy uses experiments, demonstrations, music, and silly jokes to get students tuned in to his subject matter. Despite his lighthearted attitude, there's serious science at work here, and when students hear a favorite rock song, they may sing the lyrics Nye has written in a parody for the show.
