In a zero gravity environment Liquids behave differently, making drinking very difficult. A regular coffee cup can cause hot liquid to float in the air.

As you can imagine, something like this in space is quite dangerous. Okay What is the feature of this cup?

Researchers at Portland State University have developed special cups so astronauts can drink drinks such as espresso in a low-gravity environment.

Let’s face it, the shape of the glass is a bit strange, and we wouldn’t be wrong if we said it almost looks like a toy. However There is a very important reason for its shape.

Every curve and geometric shape, to allow the fluid to move in a controlled manner designed. The pointed corner in the center of the glass is a key design feature that allows liquid to flow into the astronaut’s mouth.

As soon as the astronaut’s lips touch the edge of the glass, a capillary connection is formed and the liquid moves upward. It makes drinkable coffee balls.

Seems simple right? Even better: in a zero-gravity environment Considered how fluids move We can call it a design.

But why was there such a need?

The foundations of the project were discovered in 2008 by astronaut Don Pettit. Designed for coffee on the ISS It is based on a low gravity beaker.

After Italy announced its intention to send an espresso machine to the ISS, the Portland team set about solving the problem. Good Astronauts are tired of drinking coffee from plastic bags Such a glass has been invented
