"Invisible Sunblock" is a hands-on activity exploring how nano-scale particles are used in mineral sunblocks to increase their transparency. Visitors compare nano and non-nano sunblocks to a visual representation of the effect of particle size on visibility.

This activity encourages visitors to build an electroscope —a simplified version of one of the tools scientists use to study the invisible forces on Earth and in space. Participants will learn how static electricity works, how scientists can use it...

A short film comedically exploring the idea of invisibility cloaks and how this possible new technology may influence society.

"Exploring Properties - Invisibility" is a hands on activity in which visitors investigate how glass objects can be "hidden" in some liquids. They learn that researchers can use nanotechnology to engineer new materials that interact with light in special ways.

"Exploring Nano & Society - Invisibility Cloak" is a hands-on activity in which visitors learn about refraction and how it can be used to make a glass stir rod "disappear" in a cup of baby oil. They also learn how...
