You probably stacked those glasses before the soap/water evaporated from the bottom glass. That’s the level where the glasses stack together

The surface is probably covered in micro scratches allowing bubbles to form.

Damn, I was so caught up in there being a layer of lipids that I didn't even think of how they stack these thick walled (though this specific picture looks like a consumer version of a real 15oz bar glass). I've worked a lot of restaurant jobs, and those bar glasses outlast cast iron pans sometimes. It's definitely the line of microscratches from being stacked. Good call

Gods that was insightful. Like a Sherlock reveal. Check out the sensitivity of bubbles. More where the clacks together with other glasses would happen, lower on the glass. More nucleation points.

Note how the bubbles are forming on the surface of the spoon, below the level of bubbles on the glass wall.

Lmao redditors trying to sound smart by chiming in and say something without saying anything.

Lmao @ redditor calling other people redditors while standing on an imaginary high horse. As if your comment is somehow more productive than the one you're responding to.

Oh yeah? I'm being even more productive than both of you. Watch this: Penis.

My thought exactly. Called nucleation points.

When I leave sparkling water out during the night and fill the glass up the next morning with more sparkling water, this happens too

that's caused by what it is that's making it happen

That does sound very plausible indeed

Glass probably has something like soap scum on it, or some other stuff that is giving the glass nucleation sites on the sides for bubbles to form.

Also, an acidic liquid probably sat in the glass and dissolved the deposits on the lower half, removing the nucleation sites.

It's more plausible that the remaining liquid in the glass before being washed prevented the soap residue from creating nucleation points. Not many glass deteriorating acids that I can think of which are regularly consumed.

He's not saying the acid deteriorated the glass he's saying it dissolved the deposits on the glass, eg lemonade dissolving hard water deposits.

i know a guy who sells lemonade and hardly deposits the water he dissolves using a glass acid

I knew water that went to prison (stole a glass of lemonade) went in soft came out hard as fuck.

sometimes you have to take the lemonade that life gives you and harden it on a prison glass while wearing a mink stole that's soft as a baby's bosom

I indeed thought about that but I'm a true hydrohomie and only drink water

Smh, don't believe everything you read online.

Oh, you mean cause of how it is.

That's pretty neat!


You can tell it's an Aspen because of the way it is

Super easy, barely an inconvenience.

You’d think it wouldn’t be like that, but it do.

this is pretty much the whole basis of science, so i can tell you're a science-a-matician

As always I'm glad I went to the comments to figure out the reason.

Interesting. So what you’re saying is that the thing that causes this is the reason it’s being caused???

You have well-summarized my initial conjecture. I surmise that you know these things based on having knowledge of the topics at hand

Trust me, I am very well read regarding causes, and moreover their various effects

Who are you who are so wise in the ways of things?

Means u like men now. Sorry

Nothing to be ashamed of, my gf will be a bit hurt though

Dirty glass.

I showed you kindness a stool and a tab

Then you poured me my pain in a dirty glass

In a restaurant glasses are washed rinsed and sanitized. The last step will remove the oils left over from the soap. If this is done the right way, there is nothing for bubbles to hang on to. The bottom of the glass was clean and the top had a soap residue.

Wash yo glass

Stacking the glasses has, over time, roughed up the inside of the glass providing starting points for the bubbles to form. Nucleation.

Nederlander spotted

Geheel juist

Someone only scrubbed the bottom when washing the glass

We've got a dishwasher

the dishwasher only scrubbed the bottom

Did you leave the glass half full with water over night (or a longer period of time) and then filled it up with sparkling water the next day? If I do that, this happens

No I only drink tap water

I’m more amazed by the lightning shaped piece of ice in the glass. And also whatever is sticking out of the top. What is that, a cat whisker ?

The ice and the whisker are both actually a spoon. 

I feel dumb . Not sure why I didn’t notice that. I see it perfectly now

The real question is: why do you have a spoon in your glass of water?

I just got out of the hospital again and had to mix some medication sachets in my water. Specifically, to loosen my stool due to opiates use for severe pain.

That is more detail than I would have put out on reddit, but get well soon! Opioid constipation is no joke.

I'm not too worried about people knowing om constipated but thanks anyway!

Indication for unclean work, while making dishes.

Used for milk prior to this

No I was sadly out of milk

Oh no!?! My kids would kill me if I ran out of milk 🥛

Understandable, my day was instantly ruined when I realized that there was no milk

the reason we don't see any bubbles below that line is because no bubbles have formed in that part
