Why do they not make ice cubes out of whatever liquid they are supposed to chill, instead of water?
That is to say, put frozen cola into cola. That would prevent it from being diluted when it melts.

Some folks do. It’s just that frozen water is the “universal” coolant because water is the one reliable constituent of any beverage known. Then again, there are obvious difficulties involved with freezing vodka or tequila solid in a household refrigerator.
The freezing point changes with the concentration of solute. If we consider ethanol and water, Whiskey on the rocks anyone?, the freezing point is -23C . That would be difficult to do and dangerous for your tongue.
Many do. But as @LuckyGuy notes, the freezing point of liquids is variable.
Who is “they?” Just regular people in their homes? Some do. Restaurants? That would be a huge pain in the ass and probably not cost or space effective, considering they’d need ice for every single beverage they carry.
When I was a kid we sometimes made Coke cubes for our Coke. In my house growing up we rarely used ice cubes in any drinks, same with my husband, and in our house we have to turn on the ice maker if we know people are coming or there might not be any ice available. Many jellies have seen me write that I knew it was true love on our first date when we both ordered Coke with no ice at the restaurant. The only drink I usually put ice in is iced tea.
We make coffee cubes for our iced coffee, my sweetie uses them to cool the hot coffee because he doesn’t like to use cream or milk.
We also freeze our homemade stocks and broth in cubes to use in recipes.
They make products that will not melt and thus not dilute the beverage, like whiskey stones and plastic shapes with liquid inside them.
In addition to the above excellent reasons, water is readily available—always on tap, as it were.
Except, sadly, in West Virginia and parts of California.
Cola has a fairly low freeze point as well. Every time I’ve tried to make cola popsicles they’ve just ended up as mush.
Frozen coffee works well, though, as @hearkat said.
I do make “ice cubes” out of fruit juices when I know I will have a party and serve fruity drinks. The kids love them and it is like popsicle in a glass.
In some drinks the point of the ice is to dilute the drink.
Some people freeze stones and put them in the drink instead. There’s a certain logic to that, because the stone, being more dense than water, will stay colder longer, as well as not dilute the drink. But it’s convenient that ice melts to water, which is a lot easier to dispose of than stones. (Those things are hell on a dishwasher or drainage system, too.)
I’ve tried making ice cubes from cola before, didn’t work out too well. Was more like a slurpee than ice cubes. Which I didn’t mind, but it is messy.
Because rum won’t freeze.
Well, there you go. Take it down a bit further and use nitrogen cubes.
@CWOTUS The guys in the Fusion lab make 1 mm diameter hydrogen “pellets” at 14 deg Kelvin, approx minus 430F. Sadly they can only produce about 8 per day and cost in the 10s of thousands of dollars each so you need to be a little conservative.
@LuckyGuy
It is just ‘Kelvin’, not ‘degrees Kelvin’.
@ragingloli You are correct, of course. I write deg because here in ‘Murica some folks think plain ‘ole Kelvin is just a misspelling of Calvin or Kevin Bacon. Mmmm… bacon.
It would take up too much room in the freezer to make ice cubes for every type of cold beverage that we drink. It is just easier to use water (as opposed to other frozen liquids) because it will have the least impact on your drink as it melts. If you’re really picky about melting ice, try using frozen glasses as an alternative to ice cubes.
For parties, I will make specialty frozen cubes, but there is a limited assortment.
You know what would be good? Frozen orange juice cubes in grape juice!
I hate melted ice cream in punches. So, I usually freeze fruit juice in a mold so that it can decoratively be added to the punch bowl. Keeps the punch cool and sweetens the drink as it melts. Yum.
Pomegranate juice cubes in cranberry juice..
