Please Play! Fat Substitutes and Flu Vaccine Beckon on the Molecular Playground

UMass Amherst chemistry professor Craig Martin wants the world to know that molecules are beautiful, so he created a unique interactive molecular playground where players can twirl, flip, rotate and re-size colorful models of chemicals including a zero-calorie fat substitute and a flu vaccine. The idea has caught on. There are now molecular playgrounds at the Springfield (Mass.) Science Museum, St. Olaf College in Minnesota and at science centers in San Francisco, Spain and Japan.
