Zero Gravity & Coffee Don't Mix, Until Now!

That's right, liquid doesn't behave the same in space as it does on Earth, so the NASA scientists have run capillary flow experiments to find solutions for the issues that arise from unexpected fluid actions.

What is capillary action?

"Capillary action (sometimes capillarity, capillary motion, or wicking) is the ability of a liquid to flow in narrow spaces without the assistance of, and in opposition to, external forces like gravity."

According to the video below, the behavior of fluid in zero gravity can cause big problems.


Let's think about everything on the shuttle or space station that is fluid; fuel, coolants, drinking water, urine and yes, coffee. What happens if you design a system around gravity for an environment without it? Nothing, or at least nothing good is going to happen.


The reason, there is no UP and no DOWN. Therefore, designing something like a fuel distribution system for a space shuttle based on a gravity environment is impossible. So the geniuses had to come up with a different way.

As a result the NASA scientists have run many experiments and now they have 3 patents pending. One of those patents is for a low gravity coffee cup.

Point of interest - the patent actually mentions toasting as one of the uses for this device. Oh, NASA!

That's right, now our astronauts and all future space travelers can rest assured that their morning cup of coffee will behave.

See it in action.

Jump to minute 2:55 to see the cup in action.
