Wartburg College’s 11th annual Physics and Chemistry Demonstration Show will explore the science of pressure Saturday, Feb. 17, at 7 p.m., in Neumann Auditorium.

The event, hosted by the Wartburg Chemistry Club, Engineering Club and Society of Physics Students, is designed to engage children and adults with exciting applications of physics and chemistry concepts.

The student-led team will explore the science of pressure, including a bed of nails, a ping-pong ball accelerator and expanding marshmallows. Students and faculty will present hands-on activities in the Neumann Auditorium lobby for 30 minutes before and after the show.

The event also will be available live and on demand via the college’s live-streaming network, Knight Vision, at www.wartburg.edu/knightvision.

“We are excited to engage the local and global community. The live-streamed show is great for those who cannot be on campus; however, I recommend that people attend the live show so they can get their hands on some science activities before and after the show,” said Christine DeVries, associate professor of chemistry. “We have expanded that part to include two make-and-take activities for kids: a Cartesian diver and lung model.”

Teachers are encouraged to have their students watch the show as a classroom activity or extra credit opportunity. Those interested in making the demonstration show part of their curriculum can register their classroom at www.wartburg.edu/demoshow. Registrations must include the teacher’s name, school, class and number of students. Teachers can receive the full schedule of demonstrations.

The Physics & Chemistry Demonstration Show is sponsored by Hydrite Chemical Co.
