Taylor and Gabe go to the Franklin Institute in Philadelphia and learn that nano-iron is being used to neutralize toxins in ground water. They collect soil samples from a contaminated site, taking the samples to Penn State University to test the efficacy of nano-iron treatments.
Sarah and Mande visit the Sciencenter in Ithaca and learn that nanosilver is used in some socks to kill bacteria, keeping them odor-free. They wonder if the nanosilver in socks leaches out when you wash them, causing potential harm to beneficial bacteria and the environment. They buy two different brands of nanosocks and wash them. Then they take the socks and their wash water to Cornell University to test their effects on common bacteria.
Anil Netravali is a materials scientist who cares about the environment. He engineers earth-friendly building materials, called "composites," using parts from plants and trees. Recently, he developed a "green" skateboard that is now made and sold by Comet Skateboards. The skateboards work just as well as regular ones, but they are biodegradable--meaning they won't clog landfills.
