The cup is made out of 3D-printed food-grade plastic and has been flight-tested by NASA. The use of complex fluid dynamic geometry enhances the hydration experience that is closer to what we’re ...

ISS/NASA / SWNS. It works in microgravity by using an angled channel and capillary action to guide liquid from the cup’s base to its lip, allowing astronauts to sip beverages as they would on Earth.

That cup — called a capillary cup — is an experimental "space cup" designed specifically for use in zero gravity, so astronauts can drink freely from an open container just like they would on ...

NASA astronaut Don Pettit invented his very own Zero-G cup so that he can drink in space without using a bag and a straw. He demonstrated the invention in a video where he filmed himself enjoying ...

NASA astronaut Don Pettit designed the Capillary Cup to drink coffee without a bag and straw aboard the International Space Station. ABC News Posted: March 28, 2025 | Last updated: March 28, 2025 ...

The demo is part of NASA's Capillary Flow Experiment. Scientists say that the cup functions similarly to those on Earth by harnessing the combined effects of surface tension, so-called "wetting ...

The International Space Station (ISS), which flies approximately 400 km above the ground, has a microgravity environment, and the behavior of various objects differs from that on the ground ...

NASA astronauts aboard the International Space Station can now sip their coffee from a futuristic cup that seems to defy ... without a lid in microgravity through capillary action. Credit: NASA.

NASA has revealed the science behind how astronauts can enjoy a coffee in low-gravity in space with a special "zero-G" coffee cup. The problem for caffeine-seeking space travellers is that in low ...
