Do not put in your drink

/not sure if the statement water ice is not reusable is accurate. I am pretty sure water will freeze again and form ice, it's just nobody wants dirty ice. If these jelly cubes get dirty are you going to wash them?

That was the claim.  Would running your meltwater through a Britta make it suitable, though?  Seems a reasonable question.

whats the use case here?  am i missing something obvious?

people who put ice cubes in their drinks usually drink the water that melts from them don't they?  there's no issue of 'waste' or 'reuse' b/c you drink it.  and in the same vein you wouldn't make the ice out of dirty water anyway b/c you're letting it melt in your drink and drinking it.

and if you're NOT putting them in a drink.  like for keeping a cooler cold.  theres already a ton of non-ice cold pack options.  all of which are already reusable.

I guess the upside is that these are non-plastic and biodegradable. But I'd think that the fact that they have to be washed between uses kind of negates the potential water savings.

It sounds like it's a sponge.

That seems improbable.
We're talking a huge portion of the planet.
