MINNEAPOLIS (AP) — Hurry, hurry. Step right up to the University of Minnesota’s “Physics Circus.”

The Physics Force will present the Physics Circus, its largest show of the year, at 7 p.m. Thursday at the Minneapolis Convention Center.

The show is a mix of physics demonstrations and slapstick humor suitable for both adults and children. The show is free, but registration is requested.

The Physics Force is an outreach program of the University of Minnesota’s College of Science and Engineering. The Force consists of high school teachers and University of Minnesota physics professors and graduate students.

Among the group’s stunts is a demonstration of gravity’s effect on projectiles. It involves dropping a physicist 20 feet through the air while a friend shoots a ball at him from a cannon.
