Come one, come all. See an electron gun demonstration, watch what happens when atmospheric pressure drops in a vacuum chamber and explore the solar system. These are just a few of the demonstrations of physics effects you’ll find at New Mexico State University’s “Physics Fun Day.” If you have a sweet tooth, try the ice cream made with the help of liquid nitrogen.

Organized by the NMSU Physics Graduate Student Organization (PGSO), “Physics Fun Day” is open from 8 a.m. to 1 p.m. Friday, March 27 at Gardiner Hall at NMSU. It is free and open to the public, giving participants a way to actively explore the world of physics.
