Viagra suppositories Late last year NASA astronaut Don Pettit invented a coffee cup that will work in zero gravity!
Viagra suppositories “We can suck our coffee from a bag, viagra suppositories but to drink it from a cup is hard to do because you can’t get the cup up to get the liquid out, viagra suppositories and it’s also easy to slosh, viagra suppositories” Pettit told Mission Control while sending a video of his new invention to Earth.

Viagra suppositories “The way this [cup] works is, viagra suppositories the cross section of this cup looks like an airplane wing, viagra suppositories” he said. Viagra suppositories “The narrow angle here will wick the coffee up.”
Viagra suppositories The result: space coffee in a zero-G cup.
Viagra suppositories You’d think the hard part about drinking a liquid from a cup in space would be keeping the liquid in the cup, viagra suppositories but actually the hard part is getting the liquid out! Coffee, viagra suppositories like most liquids, viagra suppositories tends to stick to itself and the container it’s in, viagra suppositories even rising at the edge of the cup it’s in (called the meniscus.)
Viagra suppositories By making the cup come together at a sharp angle on one side Pettit gave the cup a special edge that the coffee could climb. Viagra suppositories This encourages capillary action, viagra suppositories a wicking effect to happen which delivers some of the coffee to the lip of the cup where it can be enjoyed.
Viagra suppositories Now let’s just hope someone can adapt this idea to a half-decent travel mug! Really! Please?
