Celebrating Physics with the community – is this a utopian ideal, or should it be a mission shared by every university? How can we reach out to people who would never come to campus on their own accord to learn about Physics? Can Physics Outreach become not only a service provided by an academic department to the public but also a unique learning opportunity for Physics students? We have built a diverse set of informal Physics programs which not only attract the public of all ages and backgrounds but also provide a unique growth environment for hundreds of student volunteer facilitators. I will present findings from our study on the impact of five informal physics programs on undergraduate and graduate students at Texas A&M University. We have learned that participation in informal Physics programs helps our students build their identity as physicists and boost their development through a less structured, but critically important, learning environment.
