There are much easier ways. Filtering and boiling water before freezing for instance.

Try it. That method won't work.

The easiest method known is to use an insulated, specially designed tray and follow the directions. Which do involve a serrated knife.

Tl:Dr version? There is no simple method to create crystal clear ice. Because you're modifying the behavior of how ice freezes.

Step 1: Use vodka
Step 2: Use a really cold freezer
Step 3: Profit

Get a small cooler, like a six pack size.
Remove the lid.
Fill it with water.
Put it in the freezer
Wait 24 hours
The top five centimeters will be crystal clear ice, the rest will be water.
Get rid of the water and store the ice in a different container.

That's how you make instant boiling water. When the water starts to boil you pop it in the freezer. Then when you need boiling water right away you take it from the freezer and put it in a pot. When it thaws it will immediately go back to its prior state of boiling. Ta da!

I am over 60 and for the first time in my life (since moving out of my parents' house at 18) am living with someone who actually will empty and refill the ice cube tray.

Cloudy or not, that's a win in my book!

The ice makes a crackling sound mainly because of the temperature difference between ice and the liquid, not because your ice had trapped air bubbles or structural weaknesses. The inner layer of ice is cold and doesn't expand, whereas the outer layer is warm and does expand. So even clear ice will make that crackling sound.

Don't give a rat's ass if my ice is cloudy or not.

What I care about is never buying hard plastic cube trays again...I'm a silicone convert now.

Got this silicone thingy for portioning and freezing baby food as a gift but never used it. Wife put it in the goodwill pile and that's when I had an epiphany.

Many -- MANY -- moons ago, I found an Ice Tray at my local Grocery Store.

This was not "any" ice tray. Tucked behind all the regular, boring, "square" ice trays, almost as if it'd been pushed to the far back SO NO ONE COULD FIND IT -- was a tepid, light-blue ice tray -- a SINGLE COLUMN of empty... rods.

Well I thrust my hand deep into the ice tray reservior (without haste) to grab that baby and WHAM

After committing to purchasing that little baby I took it home and filled it with water.

After the water got hard and froze I removed it from the freezer and tucked it away in a little blanket, put it in the passenger seat and drove to the beach.

By the time we'd gotten there, I kept my eye on this tepid blue ice tray -- it had started sweating from the moment I'd put it into the car, but I reassured it the Beach was not far away.

I got out of the car and went to the passengers side door (4-door car), opened it, and removed the ice tray. (It was still sweating! I'd even left one hand on it for comfort on the ride there.)

It was barely a single column of 3-inch ice "rods" that could actually fit through water bottle mouths or Gatorade bottle mouths AND it even had a 'silicone bottom' that could be pressed out to gently remove said ice "rods" from their chambers.

Then we had dinner, walked on a moonlit beach, went back to our room and made sweet, sweet love.

Are you some kind of monster? You drink it at cellar temperature, of course, because only heathens and the French keep their whiskey somewhere other than in a properly maintained subterranean vault.

Those clear little ice "half" cubes from McDonalds were good. I never got to experience uniqueness of a McDs ice Hummer.

Most people finish their drinks long before melting ice causes issues with flavor due to overdilution. Doesn't matter if it's soda, lemonade, cocktails, or a slushie. They're not buying it so they can let it sit for hours and then drink it.

A properly made drink should get the dilution it needs, as well as the proper amount of chill, when it's being prepared. The ice isn't there to keep it cold forever. It's there to keep it at the right temperature for the time expected to finish that drink.

So even if clear ice cubes melt slower and last longer, there's really much benefit from that as most people finish drinks long before dilution for melting ice even becomes a problem.

People who care about this are just another version of Audiophiles.  There is no difference between clear and non-clear ice in any practical sense other than if you're literally doing something involving shining a light through it, in which case the difference will be that it occludes the light more and nothing else.

The bulk shape and size of the ice?  Sure.  A big ball of ice has a much lower area:volume ratio than a bunch of smaller cubes, and will melt less relative to the total amount of ice as a result.  Compare a big cloudy ice-ball to a big clear one?  No human-perceptible difference.  Ditto a clear version of the small cubes versus a cloudy version of the same.

// "No human-perceptible difference" = there is technically a difference, but it requires instrumentation and extended observation with those instruments.  In the case of ice specifically... actual good instruments, even just sitting there with a stopwatch will not give you any kind of consistent difference in melting one way or the other.

// This has been today's edition of "this is literally a lab that we've made high-schoolers do in America since the 1990s, how the fark could you possibly not know this".

Swiss Colony: Whisky stones my friend.


Whiskey stones were invented with good intention by someone who does not understand the concepts of phase change and latent heat.  There is a reason ice is really good at cooling beverages.  Frozen rocks not so much.
