Gavin Murphy, a graduate student from Herrin studying music, plays the saxophone as a prank Thursday during a science lab in the Life Science Two Building. The prank is part of Slackin’ For Cancer, a weeklong fundraiser put on by the music fraternities to raise money for Race for the Cure. Murphy said that members from each fraternity take turns sitting on a bench in Altgeld Hall and offer to pull pranks in exchange for donations from passing students.
