Zero gravity coffee cup for astronauts

"Zero gravity coffee cup", coffee lovers, you haven't used it, have you? Through understanding that it is specially designed for astronauts, and the inventor is also an astronaut-NASA astronaut Don Pettit.

It is understood that Pettit tore a piece of plastic from his flight data file mission book, folded it into a droplet shape, and sealed it at the other end. The internal surface tension of this simple cup can prevent coffee liquid from floating and lateral flow. The manufacturing principle is the same as that of a rocket pumping fuel into the engine under zero gravity in space. "the cross section of this new space cup is a bit like an aircraft wing, and the narrow angle can form capillarity, making it easier for people to drink coffee," he said. "

American astronauts use their own zero-gravity coffee cups on the space station.

Petit folded the coffee cup into tears

When Pettit sent the video of the newly invented space zero gravity coffee cup to the ground, he told the space mission control center, "We can suck liquid from a special simple cup without having to drink it from a traditional cup." because in the space environment, it is difficult to use the cup and it is easy to spill the liquid out of it.
