| Experimenting with household objects
can often get young people in trouble, but for one intelligent, inquisitive boy,
it created the foundation of his future. Young Henry Ford discovered through his
curious mind that many objects were useful for much more than their intended
purposes. For example, he used to tinker with his father’s fanning tools to see
what they could do. He used his mother’s darning needles to help him repair
watches. And once, in an effort to study the power to steam, he sat and watched
water boil in his mother’s teapot. Little did Ford know that these experiments
would lead him to creating a means of transportation that would change the world
forever. Henry Ford was born on July 30, 1863, near Detroit, Michigan.
