Question

why are we able to drink coca cola from the bottle using a straw

Answer 1

due to pressure difference in our mouth and the bottle of coca cola
we suck in the air in our mouth to decrease the pressure in our mouth
and as fluids flow from higher pressure to lower pressure, we can enjoy the taste of coca cola
so enjoy different juices this summer and feel proud while enjoying them as you know the reason that how it's going into your mouth!
i hope this helps you:)
