"When you drink from a straw, you have to suck it. By sucking it, you are lowering the pressure in your mouth and inside the straw to below atmospheric pressure. As you may already know, particles move from a place where there is a large amount of pressure, to places where there is less pressure. So the drink will then move up the straw into your mouth, to balance the pressure. " Is this correct? Is there anything else i can add to it?

Its for my physics homework, i need to explain what happens when you drink from a straw, like lowering the pressure in your mouth and stuff, not blowjobs!

If you meant straws then what you can add is that "b l o w j o b s" help you practicing their use.

sounds good but you have the movement of pressures back words all ways goes from high to low not low to high that is why when you have a weather system the winds are all ways strong around a low pressure system and calm during a high pressure

yeah, its perfectly right.
you know what you can get even better marks if you explain this while a fellow student is sucking from the straw

the liquid is forced into your mouth because of increased downward pressure on the surface of the liquid you are trying to drink. this is demonstrated by the act of siphoning-- the liquid continues to flow after the suctioning stops.

just take the straw, stick it in water, and start sucking.
