did you know that when you drink soda through a straw, you’re not actually sucking the liquid up through the straw? you’re just breathing in the air at the top of the straw and increasing its velocity from 0 to however fast you’re breathing it in, which lowers the pressure at the top of the straw (since pressure decreases when velocity increases) which means that the atmospheric pressure pushing on the soda in your glass will push the liquid up the straw and into your mouth

so you’re not actually sucking up the liquid, the atmosphere is pushing it up to you
