"Exploring Materials - Thin Films" is a hands-on activity in which visitors create a colorful bookmark using a super thin layer of nail polish on water. They learn that a thin film creates iridescent, rainbow colors.
- The way a material behaves on the macroscale is affected by its stucture on the nanoscale.
- The thin film reflects differently depending on how thick it is, so you can see different colors
- Nanometer-sized things are very small, and often behave differently than larger things do.
- Nanoscience, nanotechnology, and nanoengineering lead to new knowledge and innovations that weren't possible before.
