English: Commander Jack Lousma wearing the communications kit assembly (ASSY) mini headsets (HDSTs), conducts Bubble Separation Experiment on the middeck. Lousma displays experiment in front of the port side forward middeck lockers (meal tray assemblies secured on lockers).

• Astronaut Jack R. Lousma, STS-3 commander, spins a package of colored liquid in zero-gravity aboard the Earth-orbiting space shuttle Columbia. He was actually creating a centrifuge to conduct a test involving the separation of bubbles from the liquid rehydrated strawberry powder for visible clarity. The gas from liquid experiment is a test devised by scientist-astronaut William E. Thornton. The gun-like device at center of left edge is a water-dispenser which the astronauts use in rehydrating food packets, many of which can be seen in the background of this middeck area of the Columbia. Astronaut C. Gordon Fullerton, pilot, exposed this frame with a 35mm camera.
