Mechanical Engineering students from Oregon Tech on a trip to NASA. Six students participated in the trip and the experiments, accompanied by their instructor. The photograph shows two of the students hard at work on their team's model/exhibit. The name of their project is visible on the sign in the foreground: "Immiscible Fluid Separation in Reduced-Gravity". The word "separation" is misspelled as "seperation". This photo is one of the series of 413 donated to the University Archives by Marye Hefty, Oregon Tech Communications teacher, who acted as journalist and photographer on the trip
