What Is Nano?
Nano Science is the study of things at very small scale. A nanometer is one billionth of a meter.
SELF International is bringing university researchers together with science educators to create a new and unique learning experience for young students and their families. We explore the miniscule world of atoms, molecules, and nanoscale forces. Things can behave very differently at the nanoscale.

The Blue Morpho Butterfly
The Blue Morpho's wings have very small overlapping scales covered with tiny "ribs." The size and arrangement of these nanostructures makes the wings look blue - but they're actually transparent! There's an air space of a few nanometers between the ribs. Light waves bouncing off the top and bottom surfaces of neighboring ribs interfere with each other. Most light waves are cancelled by the interference and only certain wavelengths - seen as colors - bounce back to your eyes. So when you look at the front of the butterfly, it's a beautiful, iridescent blue (as seen above).

Super-Hydrophobic Properties
Nano scientists study plants which have natural water repellency to discover how to create water repellent fabrics and other materials.
