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.
Campers at the Austin Children's Museum will be learning about molecules and mixing up a batch of polymer slime this summer, as well as extracting strawberry DNA, and doing the liquid crystals activity from the NanoDays kit in the museum's Girls Explore Science Camp.
It's all-summer-programming-all-the-time on the Nano Bite this week. Here are a few examples of how partners are incorporating nano topics into their regular summer programming:

As I mention in the June Nano Bite newsletter, lots of NISE Net partners are either planning nano-themed summer camps or using nano activities from the NanoDays kit or other sources in their camp programming.
I'll be posting examples all this week, here's one of an entirely nano summer camp program:
