Question

will you be able to drink juice through a straw on the Moon?give reason

Answer 1

When you suck water up a straw, you are not really pulling it up the straw. You are just moving some of the air in your mouth out of the way, creating a slightly lower pressure. Since air is pressing down on the water in the cup, it’s forced up the straw until the pressure differential is equalized.

You could perform an instructive experiment, but I can tell you what will happen. The experiment is this:

Get yourself a cup with a lid with an integral straw.
