Hi everyone !
My physics teacher showed us this thing he made and then asked us “why does the water shoot up out of the straw at the top”? No one knew the answer and he did not tell us the answer. And this has been bothering me for almost 2 weeks now (keep reading and it will make more sense . . . I hope).
My teacher took two soda bottles (you know the liter ones). He glued 2 straws in the inside of them and filled one about half way with water (i know this sounds really weird but the drawing will make more sense. . . hopefully lol). He glued them on top of each other and then turned it upside down so the one with the water is now on top. The water goes down into the bottle on the bottom but water shoots out of the straw on the top. Yeah I know your are probable thinking to yourself that this girl is crazy and makes no sense whatsoever lol. I'm sorry but it's hard to explain in words what he did. Why does the water shoot out of the top of the straw that is in the top bottle? What causes the water to shoot out of the straw? I know it has something to do with pressure. I hope the drawing makes more sense. lol
