Astronaut Don Pettit worked with engineers at Portland State University to develop this 3D printed cup based on his simple design made in November 2008 on STS-126. Using thin plastic film and kapton tape, he fashioned one for each crew member on the International Space Station. Pettit used his understanding of surface tension and capillary flow in space to force liquid to flow down the narrow channel on one side towards the opening of the "cup." Pettit and engineer redesigned that into this more elegant 3D printed version, which flew to space in 2012. Versions of this cup have been used in space since that time.
Dr. Don Pettit donated his original cup to the Museum in 2023.
