Richard Byrne writes: "One of my former colleagues always seemed to have his physics students in the hallway, in the stairwells, or outside for various physics demonstrations. His students always seemed to be having fun. I was a little jealous that he hadn't been my physics teacher too. He showed students that physics was fun. The following games might not be as fun as hands-on demos, but they could still be good for getting students interested in various physics concepts."
