Nebraska’s sixth annual “NanoDays” is 1 to 4 p.m. March 28 at Gateway Mall, 60th and O streets.

“NanoDays” is a nationwide festival of educational programs about nanoscale science and engineering. Nanoscientists transform the world with materials smaller than the eye can see, and at “NanoDays,” interactive demonstrations and games will introduce attendees to the magic-like properties of nanomaterials.

The first 100 student attendees who visit each of the stations will receive an “I Heart Nano” T-shirt, and the elementary school and middle school with the most attendees will win a nanoscience education kit.

At “NanoDays,” UNL faculty, staff and students and Lincoln Public School educators offer fun learning experiences for children and adults. Event demonstrations show how researchers use the minuscule world of atoms, molecules and nanoscale forces to invent technologies like the invisibility cloak, a liquid that becomes body armor and floor tiles that generate electricity when walked on.

The event is co-hosted by Nebraska EPSCoR, the University of Nebraska’s Materials Research Science and Engineering Center and the Nebraska Center for Materials and Nanoscience.
