In this episode, we dive into the mystery of Minnesota’s Devil’s Kettle—a waterfall where half the river disappears into a deep hole and doesn’t seem to come out. For years, scientists, hikers, and mystery-lovers tried to solve it. Did the water vanish into a secret cave? A hidden lake? Or somewhere stranger? Listen in as we explore one of the coolest natural puzzles in North America. Recommended for ages 10–13.
