The Magic School Bus (1994)

S2E6 Wet All Over

Arnold and Wanda are set to present their report on the town’s waterworks when Ms. Frizzle declares it’s time for a field DRIP adventure! She transforms the bus and the class into water droplets, leading the children through an exhilarating journey of evaporation, condensation, and rainfall, ultimately flowing into the ocean. After experiencing multiple stages of the water cycle, they realize they need a magic key to return to their normal selves, but it’s locked in the school bathroom. As they navigate through the town’s waterworks to find a way into the bathroom, they learn about water purification. Will they make it back to school, or are they destined to remain in the water cycle?
