Ben Franklin loved to swim and, at the age of eleven, he was determined to swim like a fish - fins and all! This fascinating and lively account of young Ben's earliest invention follows the budding scientist's journey as he tests and retests his swim fins. That first big splash led Ben to even more innovations and inventions.
