How Do You Drink Coffee In Space? With A Zero-Gravity Coffee Cup, Of Course


On Earth, liquid coffee depends on gravity for its brewing process. Hot water drips onto fresh grinds, which strips the oil from the beans to create the cup of joe you rely on for that early-morning pick-me-up. Without gravity, however, brewing a cup of coffee is challenging, but so is finding a way to actually drink the caffeinated beverage once its brewed.

“The coffee would be very hard to control,” said physics professor Mark Weislogel of Portland State University. “In fact, it probably wouldn’t [come out of the cup]. You’d have to shake the cup toward your face and hope that some of the hot liquid breaks loose and floats toward your mouth.”
