Interesting. That’s the main reason I avoid tap water, I can taste the stuff that’s in it. It’s almost a little metallic. At the very least I use a filtered pitcher.

Cool. Tap water looks like river water. I drink my tap because it is well water and it tastes so much better and is naturally filtered. If I had to choose between those I’d choose the filtered though.

I should have mentioned
both of these glasses of water had gone to room temperature
they were here at my desk for a few days
I just found it rather shocking.
Yeah me too. Not surprising though. Just s bit unsettling ha.

Your water looks weird.

Ha! I don’t know, but water is in the news here
we’re getting flooding the next few days.
That’s just air. Cold water holds more gases that are released when it warms up. The tap water was probably colder. Or maybe the air didn’t stick to the other glass for some reason.

Phil thought that too, that it might be a difference in glasses
but no, both were set out for a day or two before I cleaned them up
I don’t have soft water from tap either
The cups might be different. Try reversing the experiment with the same two cups. Filtered in the right one and tap in the left one.
Also, oxygen is used in cleaning water. It removes foul-smelling molecules and makes the water taste better. If you get the same result with the reversed experiment, I would expect the tap water to actually taste better. Water is supposed to release gases when it warms up. In tap water, those gases should be mostly nitrogen and oxygen, like in air.

One place I used to live was on city water and I didn’t like the way it tasted so I drank a lot of Kool Aid to mask the taste. I grew up in the country drinking well water and that is what I am used to.

one was cold filtered water gone to room temperature. the other is cold tap water, not quite at room temperature.
I don’t see a big difference. One has air in it. Filters remove air.

this tap water has been set here for up to a half an hour.
The filtered water has been set here for over 5 hours.
Trust the bubbles.
The bubbles are good.

is there an angry button.
Water with oxygen and gases removed is not as good for you as the regular kind with bubbles. Think of it as dead. Animals in the ocean avoid areas with low oxygen dissolved in it and will suffocate. The bubbles feed your insides and shouldn’t be removed.

Why do bubbles form if a glass of water is left alone for a while?
Here’s a Scientific American article with the explanation.

thanks, @Moonbeam
the last pic I posted
the bubbly water was in a hard plastic cup
it isn’t a glass
you notice also when you first pour coffee it gets kinda bubbly
then goes away. hmmm. Yeah, I think we got it all hashed out now. ha.
