I was discussing this with some friends yesterday, and we’ve basically narrowed it down to three contenders. In order:
- Salt
- Ice
- Copper ore
Rules:
Going by dictionary definition of “rock”, which means “stone”, which means “mineral”.
Water is a mineral according to the dictionary, which is why ice is in there.
Minerals are inorganic according to the dictionary, so things like sugar crystals don’t count, since they’re organic.
So, is it one of those three, or are there other delicious rocks that we’ve overlooked?
Halite is a boring answer, but Potassium chloride (“No Salt”) is a fun rock to taste. Ice prepared with heavy water is the only sweet-tasting mineral that comes to mind.
Sal ammoniac is another fine-tasting rock. Copper ore might be the worst of the options here, I hate the taste of copper in drinking fountains.
Really? I quite like the taste of copper. I have a copper pen and it’s delicious.
