In the magical land of South Dakota, where bison roam freely and the wind whispers tales of ancient traditions through the Black Hills, there are children filled with an insatiable curiosity. These aren't your ordinary kids, oh no, they're members of the Secret Society of Experimenters - or SSE for short. They have the knack of turning the ordinary into the extraordinary in the most remarkable ways. Take little Billy Bison, for instance. His wild, brown curls spring out in all directions as he's always thinking up new experiments. Sometimes he's mixing up concoctions that bubble up and overflow with colors of the rainbow, while other times he's creating whizzing rockets out of corn cobs. Then there's Sally Sunflower, a girl as bright as the sunflowers that grow abundantly across the state. When she's not trying to invent a sunflower that grows hot dogs, she's probably racing her ferret on a homemade rollercoaster. And who could forget mischievous Molly Mount Rushmore? She's always trying to replicate the historical monument using mashed potatoes and gravy at dinnertime. Much to her parents' chagrin, they often find themselves dining in the shadow of her edible sculptures. In South Dakota, there's never a dull day. Here, every grain of sand, every blade of grass, and every twinkling star in the vast prairie sky is a chance for an exciting experiment. The children of SSE are here to prove that science isn't just a subject in school, it’s a way of life, and there's always a new adventure waiting just around the bend.
