Zero-G Drinking Cups - Impressive Technology
Astronaut Don Pettit demonstrates the new zero-g cup developed on the International Space Station. Using capillary technology, Pettit has developed an open-topped cup that holds liquid in zero gravity. This design allows for astronauts to drink out of the cup without a straw and without gravity to hold the liquid in the container.
This same technology is used in rocket engines to ensure continual fuel flow in zero-g. So I guess Bistro-ISS is officially open for business. There have been no official reports of testing with carbonated alcohol in orbit as of yet. I guess they are still waiting for the pint-sized prototype.
