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.
- Nanotechnology is the science of the super-small.
- Nanomaterials have different properties than the same materials at a larger size.
- One reason for these different properties is an increase in surface area.
- Nanometer-sized things are very small, and often behave differently than larger things do.
