In 2015, astronauts brewed espresso in orbit and drank it from a 3D-printed cup; surface tension pulled the coffee toward their lips without gravity

Astronauts can now drink coffee normally in space thanks to a special 3D-printed cup. This innovative design utilizes capillary flow to move liquids without gravity's assistance. The space cup allows astronauts to sip coffee directly from the rim, a significant improvement. This technology, developed by NASA, also aids in moving liquids in other critical applications. The invention demonstrates how simple physics can solve complex engineering challenges in space.
