Penn's oldest residential program, the Science and Technology Wing (STWing), held its annual Rube Goldberg competition this past weekend. The competition pit teams of students against each other to build a device that could dip an Oreo into milk. Judges included MEAM professor Dr. Mark Yim, CIS professor Max Mintz, and MEAM lecturer Graham Wabiszewski. STWing is celebrating its 25th Anniversary this academic year.
