Ultrafine bubbles

Bubbles, they come in all shapes and sizes; bubbles contained in a liquid are visible to the eyes when the bubble sizes are large enough, as we can see bubbles in carbonated drinks. Bubbles with the size of a few millimeters in diameter show visible surfacing action in a liquid, and the presence of fine bubbles of dozens of microns in diameter can be confirmed with white turbidity in a liquid, because these bubbles are scattering substances.
