- In what ways is Rubner’s new coating like the surface of a lotus leaf ? In
what ways does it differ from a lotus leaf surface? For information about lotus
leaves, see www.iop.org/news/910 (Institute of Physics) or www.fy.chalmers.se/projects/biocompatiblematerials/

- Where in the world would an anti-fog coating be especially important or
- Write a commercial for television promoting Rubner’s new anti-fog coating.
- When scientists or engineers invent something that might have commercial
value, they have to patent it. How does a researcher go about doing this? What
do applications for patents look like? What kind of information does theresearcher need to provide? See www.uspto.gov/go/kids/.
Three friends have a container that holds 24 ounces of water. They have three empty jars, one that could hold 5 ounces, another that could hold 11 ounces, and a third that could hold 13 ounces. Using the available containers, how could the three friends divide up the water so that each one gets the same amount?
