Each Saturday, this popular program draws over three hundred children and adults from southeastern Michigan to learn about the mysteries and wonders of physics. UM professors from several departments present topics ranging from black holes to astrophysics, from MRI technology to human genetics. Multimedia demonstrations, hands-on experiments, and audience participation make the mornings a lively give and- take between professor and audience. The 6-8 week spring season builds on the success of the program run each fall. An endowment of $500,000 would allow the spring season to continue in perpetuity. It costs the Department $25,000 annually to produce the spring season, which includes professional videotaping of the sessions for distribution on public television.
