Ok, so I've been elected president of my department's Society of Physics Students (SPS) and I'm looking for physics or science-related things to do, or rather, things to keep people coming to the meetings. For our next meeting, we're going to draw up a draft for a campus-wide egg-drop battle between the science departments. I was thinking about doing something similar with a mini triathlon in the spring. So between that, ordering new t-shirts, sponsoring my lecture series and nights of taking the department telescope out for observing, what other physics, astronomy or science-related things could keep people interested in coming back to meetings? Any ideas?
