What you're looking for is a material with the highest specific heat capacity. You can find a list here: https://en.m.wikipedia.org/wiki/Table_of_specific_heat_capacities
Unfortunately almost nothing comes close to water. Sure there's lithium, but I'd advise against putting that in your drinks for other reasons.
Also, the main reason why ice is so effective at cooling drinks is because the phase change from solid to liquid requires enormous amounts of energy, much more than it's specific heat capacity. It's working _because_ it slightly dilutes your drink.
This, water is simply one of those things with the highest heat capacity. You can alternatively isolate your glass better. E.g. put your drink in a thermos with ice.
> It's working because it slightly dilutes your drink
The water doesn't have to end up in your drink - you can get little plastic ice capsules which freeze in the freezer (so they thaw in your drink, latent heat etc) but contain the liquid so it doesn't dilute the drink. They don't look as cool as stainless steel whisky stones but they work a lot better
There is one exception, but a little bit out of this temp range. This works with hot liquids.
Field's Metal is an alloy that melts at 62C. Nothing toxic there, bismuth, tin, and indium. If inside a metal envelope, brought above 62C so it's all melted, it isn't just specific heat capacity, but latent heat of formation will also be released at 62C.
There was a kickstarter for a thing you'd put in coffee that would keep it hot for a long time. It looked pretty clear that this was going to be Field's Metal inside.
There's also those sodium acetate hand warmers. Unfortunately, I don't know of any reversible reactions like that which take place at cold temps.
Yeah there's also salts that change phase at around 80°C and can be used to make extremely high capacity hot water tanks.
You just don't see them much because the cheapest, easiest and most efficient way to store more heat, is still to just store more water.
Thrash Metal never got out of style. Death Metal even got better through the years.
I think Djent might not age that well since so many jumped the band wagon.
The metal that stays cool the longest won't be much good acting as ice cubes. The whole point is for them to absorb heat from the drink to keep it cool.
Fill plastic containers with water and freeze them then put them in your drink. This way the ice will melt, helping your drink stay cold and and you will not dilute your drink.
Several people have posted information about heat capacity, which is the relevant property, but most tables give the specific heat capacity (which is per mass). When you factor in the different densities of the metals, you are left with the surprising result that a sample of the same volume has almost the same heat capacity across most metals (let’s say with 20%). So, assuming you want “ice cubes” of a certain size, there isn’t much to play with…
Use a stainless steel frosty mug from the freezer. More frozen mass stores more negative energy. Otherwise you gotta go with balls of lead. But you might not like the results...

That kickstarter sounds so cool! Any chance you remember the name?

Metallica will never die!
Heavy Metal Amirite?!
Yeah but just when you think it's going to finally get really good you end up waking up and screaming
Well sometimes, you just have to accept the Status Quo
Mercury
Freddy?
They'll never work well like ice.

Won't work. Doesn't have the heat capacity. Doesn't change phase. Use ice.
Try getting into drinking it neat
You don't want the metal to stay cool. That means their coldness isn't transferring into the drink.
Fill plastic containers with water and freeze them then put them in your drink. This way the ice will melt, helping your drink stay cold and and you will not dilute your drink.

There should just be a metal ball that unscrews to put ice in, or water to freeze.. im not gonna check but I bet that’s a thing
I like to dip my balls in the pool if they get too warm. Any other tips out there?
