Explanation:
When you drink from a straw, you create a little space of low pressure inside your mouth and in the top of the straw. Then the air outside the straw pushes down on the surface of the drink and forces the liquid up through the straw and into your mouth.

Answer:
Explanation:
The atmosphere pushes the liquid in the glass up into the straw. ... When you inhale through the straw, you take the atmosphere out of the straw.
