Visitors to the Sciencenter in Ithaca, NY, are blowing bubbles and exploring the nanoworld at the same time.
Visitors to the outdoor science park investigate the properties of bubbles, structures that self-assemble from soap film. They also create large soap films, observing that the colors of the film depend on its thickness. Summer campers are using clear nail polish to make rainbow-colored thin films that won't pop.
