Need help with informal rush

At my university we have fall (formal) and spring (informal--C.O.B. like). This spring though there are new rules...to make a long story short, we need sisterhood like activities to do (instead of skits). We will be having house tours one night and the other three nights of rush need to be non alcoholic activities in our sorority house. We need ideas, like a movie night or something... HELP!!!!!
