While other children played with standard toys, young Margaret Knight preferred the feel of wood and tools in her hands. Growing up in the 1850s, she built the fastest sleds and the highest-flying kites in her entire town. By the time she was twelve, she was already working long, exhausting shifts in a noisy cotton mill. When she witnessed a dangerous accident caused by the heavy weaving looms, her sharp engineering mind immediately went to work. She invented a clever safety device to protect the workers, sparking a lifelong passion for creating new machines. You will see how her brilliant ideas led to over ninety inventions, including the incredibly clever folding machine that created the flat-bottomed paper bags we still use in grocery stores today. Discover the amazing true story of a trailblazing woman who proved that brilliant engineering knows no boundaries.
