This expedition also used the ISSpresso machine and tested a special cup designed to be drunk from in microgravity by using capillary flow.{{Cite web|url=https://www.nasa.gov/feature/national-coffee-day-java-in-zero-g|title = National Coffee Day: Java in Zero-G|date = 29 September 2015}} This was a further development of a zero gravity cup invented by astronaut Donald Pettit and tested on ISS in 2008.{{cite web|url=http://dvice.com/archives/2009/02/astronaut_inven.php|title=Astronaut invents coffee cup for a weightless cup o' joe|author=Charlie White|access-date=2009-08-31|archive-date=2011-07-23|archive-url=https://web.archive.org/web/20110723033115/http://dvice.com/archives/2009/02/astronaut_inven.php|url-status=dead}}{{Cite web|url=https://science.nasa.gov/science-news/science-at-nasa/2015/10jul_spacecoffee|title=Space Coffee | Science Mission Directorate}} The new zero g coffee cup idea was further developed by a Fluid physicist at Portland State University among others.{{Cite web|url=https://science.nasa.gov/science-news/science-at-nasa/2015/10jul_spacecoffee|title=Space Coffee | Science Mission Directorate}}
