"The Magic School Bus" is an award-winning, animated children’s television series based on the book series of the same title by Joanna Cole and Bruce Degen. It is notable for its use of celebrity talent and being both highly entertaining and educational. The only contribution the kids in Ms. Frizzle's class have made to the Walkerville Space Capsule is an empty jar. But they soon discover the jar isn’t empty; it full of air. They learn the power of air when the bus shrinks and gets stuck inside the jar, and the class finds that their only hope for escape is... air.
