A straw is a type of simple machine known as a lever. When you suck on a straw, you create a pressure difference that allows liquid to be drawn up through the straw. The straw acts as a lever arm, facilitating the movement of the liquid from a lower to a higher position with minimal effort. Additionally, it can also be considered a form of a siphon, as it uses atmospheric pressure to help draw the liquid up.
