Have you ever taken apart a wristwatch? It contains gears, springs, and screws -- basic mechanical elements skillfully built using the wisdom and technology of humankind. You'll realize that watches are able to tell time because of a complex combination of these basic mechanical elements. These same elements also underlie modern science and technology. This room contains basic mechanical elements and devices that apply these elements. By playing with them and operating them with your hands and feet, you will come to understand, through experience, the functions of these machines and their underlying principles. Not only will you discover that the machines around you consist of combinations of mechanical elements, but you will also find yourself wanting to make new machines.
