Question

Will we be able to drink juice through straw in planets other than Earth ? Why ?

Answer 1

A drinking straw is a long plastic or paper tube through which a drink is drunk by suction. Drinking straw decreases pressure inside the container. When air is sucked out of a drinking straw,the air pressure inside it decreases and the atmospheric pressure out side forces the liquid to go inside the straw.
But it is not possible in other planets. In the absence of atmospheric pressure, juice is never sucked through straw into mouth.

Answer 2

In the current discovered planets of our solar system it is not possible to drink juice other than Earth because in planets of our solar system there is no atmospheric pressure on them that isn't sufficient to drink juice, the juice will spread all over in the air.
