This 5-minute video adapted from NOVA scienceNOW explores the potential of carbon nanotubes, whose strength and unique properties make them useful for a variety of applications. See animations of how carbon atoms bond to one another in different ways to make diamond, graphite, buckyballs, and nanotubes. Consider how a seemingly impossible application, such as an elevator from the surface of Earth to space, is now theoretically possible given this revolutionary new building material. Editor’s Note: Carbon nanotubes are members of the fullerene structural family, which includes buckyballs. They are the strongest material yet discovered in terms of tensile strength, though product development is still in its infancy. The potential applications for carbon nanotubes are impressive, especially in fibers, electrical circuits, optics, and medicine. This resource includes background information for teachers and suggested discussion questions.
