The Physics Force,  an outreach program of the University of Minnesota's College of Science and Engineering, will present the Physics Circus, its largest show of the year, 7 p.m. on 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, registration is requested. 

 The Physics Force consists of high school teachers and University of Minnesota physics professors and graduate students. What can you expect?

One fun idea is dropping a physicist 20 feet through the air while a friend shoots a ball at him from a cannon. No, really, they are doing that.

Tickets available at EventBrite.
