Airlift pump

An airlift pump is like a big straw that sucks up water or other fluids from one place and moves it to another place. It works using air bubbles. Imagine blowing bubbles in your juice with a straw; the bubbles make the juice move up the straw and out of the cup. That's how an airlift pump works!

First, we need two containers. One container is filled with the water we want to move and the other container is filled with air. We connect the two containers with a tube, which goes down into the water.

Next, we pump air into the bottom of the tube, which makes bubbles form in the water. These bubbles rise along the tube, and as they rise, they carry some of the water with them. The upward force of the bubbles makes the water come up from the first container and into the tube.

Eventually, the water reaches the top of the tube and spills over into the second container. The air that was pumped into the bottom of the tube is then released into the second container.

And that's how an airlift pump moves water using only air bubbles! It's like magic, but it's really just a clever use of physics.
