There's been some debate about the safety of nano-sized particles of zinc oxide and titanium dioxide in sunscreens-- one of the scenarios discussed in the NISE Net's Nanomedicine in Healthcare forum relates to using nano-sized particles of zinc oxide in sunscreen. However, one consumer group recently weighed in that maybe nano sunscreens are okay.

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.

There's nano in that summer camp! Part 1

I'll be posting examples all this week, here's one of an entirely nano summer camp program:
