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.
