I have a half-cut plastic bottle with a balloon sheet attached at its end. I also have a water bottle and now what I'll do is I will pour some water in this half-cut plastic bottle. I want you to see what happens. Where do we see the balloon sheet bulging? Why does this happen? We can say that this happens because we are pouring water from the top right? But let's use some scientific words to explain this. We can say that the pressure from the water causes the balloon sheet to bulge. And as we pour more water, more bulging is seen. So the amount of pressure at the bottom also depends on the amount of water added. Let's take one more case. Here I have a plastic bottle with two holes on its sides. These holes are the same height. And now I will pour some water from the top and I want you to think about what will happen. Alright, we see two streams of water come out from the sides. We also see that they cover almost the same horizontal distance. Well almost the same. Maybe the holes were where it had the exact same height. So this tells us that the water not only exerts pressure at the bottom but also on the sides. And since the stream of water cover almost the same horizontal distance, this shows that the pressure exerted on its sides which are at the same height is also the same.
