All I learned was how to make iced coffee

But do the gills use movement, energy from the movement, like the flap to trap the mini bubbles inside the gills?

This is wrongwrongwrong. Gills are not filters. They are organs that extract oxygen from water and release CO2 into it with gas exchange. Oxygen is part of water itself, not something suspended in it that can be removed with a filter.

This is not experiment but simply a show that proves in no way that fish allegedly breath oxygen from water. Using the word "pretend" says alot about this fake show.
