When Assistant Professor Matthew J. Lang took this plunge last Friday, Aug. 12, graduate student David C. Appleyard had his camera ready. Lang and Appleyard were attending the annual barbecue for MIT's biological engineering and chemical engineering departments, which was held in the East Campus courtyard. The dunk tank, which was used to raise funds for a local food pantry, was one of several activities at the cookout, which also featured jousting and an obstacle course. Photo / David C. Appleyard
