Pascal's law

Pascal's law is like a game of ping pong. Imagine you have two ping pong paddles and a ball. When you push one of the paddles, the ball bounces back to the other paddle.

Now imagine those paddles are actually containers filled with water instead of air. When you push down on one container, the water inside it will push back against the walls of the container. The pressure created by this push is what Pascal's law is all about.

Just like the ball bouncing back and forth, the pressure in one container can be transferred to another container through a connecting tube. This means that if you have two containers, one big and one small, and you connect them with a tube, the pressure will be the same in both containers.

But wait, there's more! Pascal's law also tells us that if you increase the pressure in one container, the pressure will increase in all connected containers. So, if you have a bunch of containers connected with tubes and you pump more water into one of them, the pressure will increase in all the other containers too.

Overall, Pascal's law tells us that pressure created in one point of a fluid (like water) can be transmitted throughout the fluid and affect other objects or containers that the fluid is connected to.
