This is a large group version of the Surface Area program. In this interactive stage presentation, audience members are measured in nanometers and demonstrate the effectiveness of "nano" silver in killing germs. Other highlights include a fireball that starts and ends the show. Visitors learn that nanoparticles behave differently, in part because they have a high surface area to volume ratio.
Duke University researchers explain the relationship between nanomaterials, in particular nano silver, and their potential impact on the ecosystem. To see the video and learn more about the Center for the Environmental Implications of NanoTechnology at Duke, visit the resources tab.
