I have heard the same. It never made sense to me. But I never tried to prove or disprove it.No. And I’m not sure why the hell I’m doing it.
The old man told me when I was kid that boiled water freezes faster and clearer because it releases trapped air.
Pretty cool.I got a clear ice cube doodad today and will be playing around with it in the work fridge. I'll post the results, as work and the holidays permit. Since it's mid-December and I'm running all over the place for work, have some patience.
First attempt is with tap water. I'll play around with filtered water, bottled water, etc.
This is what I got off Amazon to play with. It makes 10 spheres at a time, 1.7 inches in diameter:
Interesting, I’d love to get a needle in there and determine what’s in the bubbles. As it cools the water shrinks, so increases the vac and maybe creates bubbles? Just a guess. exactly the opposite of what I predicted.Test was a failure. Purified water on the left, distilled on the right. Both had a small cloudy center but the odd part was the large bubbles inside the blocks. Both jars remained in tact and were still under vacuum when removed from the insulated lunch box.

Call it abstract ice and it will make the drinks cost more 🤣Test was a failure. Purified water on the left, distilled on the right.

Try stroking the cylinders of ice. Post the video.
It’s complicated, but water contracts as it cools until a few degrees before it freezes then it starts to expand.I've always been under the assumption that water itself expands when freezing.

We used t get "bubbles" in clear polycarbonate parts that were actually shrink voids, instead of bubbles. The material would shrink while cooling and pull the voids in the material. Might be something similar happening.
had one leak all over the counter when it badly needed a cleaning and descaling. Forget the brand, GE has since bought the company.Admittedly skipping over much of this thread…. But….
wife had a counter top nugget ice machine that shit the bed the other day and started leaking. Looks like the things have gotten cheaper. I saw one that advertised clear cubes for ~$300. Interested….
micro bubbles.
Pretty cool.
How big is that damn thing tho?

It's in the refrigerator freezer at the shipyard where I work, filled with tap water. But I'm currently at the naval base this week. I'm planning on swinging by after work today to grab something else I need and if I remember, I'll take a look and see how things work. I'll post pics.
Got back to the office this afternoon after work at the base. Checked the cubes.
I THINK @GoWolfpack used DI water when he refilled.
The cubes came out nearly crystal clear, with just the faintest hint of air in the very bottom.

I kept forgetting to update this thread. I used the hottest hot water from the tap to fill the bottom and distilled water for the tray.
Sweet!
I'm thinking of we took the aerator off the faucet, that might help.
One of the sinks in the first floor bathroom is missing the aerator.
After staying in a hotel that used laminar instead or an aerator I’m thinking about switching my house out to them.
They remove all the air instead of adding it.
Jesus. You’d need a small chest freezer just to house one of those things. lolGHOST ICE
