When can coffee be drunk in space?
When you use the Zero Gravity Coffee Cup. As reported by Mashable, without gravity, it’s really tough, but not altogether impossible, to predict how a liquid will behave. So taking an attempt to develop a better understanding of fluids in microgravity, a Capillary Flow Experiment is in the process of being conducted onboard the International Space Station. Earlier it wasn’t possible to drink in free space, as the laws of gravity don’t apply!
But now using their research, Professor of Physics Mark Weislogel of Portland State University and his colleagues have been granted a patent for a Zero Gravity Coffee Cup. Astronaut Don Pettit, who also worked with the Capillary Flow Experiment during his time on board the ISS, helped invent the cup. One side has a sharp interior corner and capillary forces send fluid flowing along the channel and into the person’s mouth without floating in air,
They have revealed that as a person sips, more fluid keeps coming, and the coffee can be enjoyed in a weightless environment, completely down to the last drop. A celebration in space — no problem!
