Ok I'm back! Let's do this :) And make sure you subscribe to my YouTube channel so you can catch my new videos about this project!
I like how the three bubbles get smaller as they go up. Technically, they would get bigger if each has the same volume of air because the higher the float up, the less water pressure surrounds them and so they would expand. But I like to think that they get far enough in the distance as they go up that you're actually seeing them in perspective so they look smaller even though they're getting bigger. Sorry to science you when you usually come here to get arted.
