Magic School Bus: Molecules and Cleaning

The video follows a class on a field trip with Ms. Frizzle, where they plan to meet a music star, Molly, by washing her car. During the car wash, they learn about the role of soap and water in cleaning. The class shrinks to explore molecules and solve a tar problem on Molly's car. They also discover the mystery of a sugar crystal hood ornament. The video concludes with a concert performance dedicated to the class.
