Each spring Dale Stille, Instructional Research Specialist in the University of Iowa Department of Physics and Astronomy, coordinates the department's highly anticipated and free Public Demonstration Show, with the help of student volunteers and Professors Vincent Rodgers and Greg Howes. The 2019 show was March 15. Much time and preparation and after hours work goes into the event. It is held in Lecture Room 1 of Van Allen Hall, which seats 304 and is filled to standing room only.

This year's show explored nature's rhythms, showcasing quantum clocks, waves, frequency, sound and audience waves, acoustic levitation, signatures of gravitational sound waves using sound and a vortex cannon, and much more. There were hands-on displays in the lobby for kids before and after the show, and Stille drew for raffle prizes for the kids during the show.

Keep your eyes peeled for next year's show!
