“Turn on the propane first with this knob, then turn this knob for the oxygen.” A flame, half a foot long, bursts from the nozzle. That was Sally Prasch, a scientific glassblower of the UMass Glassblowing Laboratory. In February, the Student Event Committee organized three workshops at the lab for Smithies to learn the unique craft of glassblowing, an intersection of art and science that cannot be found on campus.  Sally Prasch demonstrates how to melt the end of a glass rod.
