During a school dance event, a group of friends—Mia, Toby, Lily, and Ben—discover that the music player is broken. Together, they use their knowledge of circuits, belts, friction, and sound waves to troubleshoot and repair it. They replace a slipped belt with a rubber band, reconnect a loose speaker wire, and successfully restore the music. As they test the fix with dancing, more students join in, creating a lively, shared celebration. The principal commends their teamwork, and the friends record their repair steps for the future, ending the day with a sense of accomplishment and joy.
