Not the eye kind. The drinking kind.
Hospitality in zero G isn't exactly elegant. Astronauts drink from pouches through straws - rather like those juice pouches most of us took to grade school.
The Cosmic Lifestyle Corp wants to change that, by designing glasses that work in space. It works in a similar way to some rocket motors - grooves hold the fluid in the glass and keep it from floating away...except into the drinker's mouth.
Unfortunately, it doesn't appear that their kickstarter has worked out - with 4 hours to go, they've only raised a bit under $3.5k. They're now going to try an alternate means of funding. (Although it's a great project, their rewards aren't very good).
