Why does clean water matter so much? Ms. Willow’s class didn’t know either—until today. What starts as an ordinary science lesson turns into a wild journey through sinks, sewers, ancient cities, and swirling pipes of mystery.

It’s a magical, science-powered field trip through sinks, rivers, and time itself!
