Title says it all. And I’m not talking about cloudy water. Just the stream itself looks white when it gets to a certain speed. When it settles in a cup it looks the same. Does it bubble when it moves or something? Why would there be bubbles from the faucet? I just don’t get it. (‘:

The other answers are correct, but more simply, take a picture of the underside of the facet where the water comes out (with the water turned off). Usually there is a metal screen of sorts that screws on to the end of the faucet, not exactly sure why tbh. But getting into the laminar/turbulent flow mentioned in the other comment, when the water is flowing slowly, it easily passes through the metal screen without much disruption (imagine a slow moving stream going through rocks), but when you turn the water up and it’s going faster, the water collides against the screen harder causing the molecules to bounce, leading to turbulent flow (like fast moving rapids of a river where people go white water rafting). The water bouncing around causes bubbles to form as the water comes out, combined with the turbulence, which causes light to not easily pass through the water, making it appear white
