Wow, the vinegar actually worked! You wouldn't think vinegar could dissolve limestone, but I guess it does, just slowly.
acids attack bases. it forms calcium acetate and carbon dioxide. the former is quite interesting as it easily forms super saturated solutions, plenty of videos on youtube featuring it.
and there doesn't have to be anything slow about it. the only reason household vinegar is so slow is that it is very diluted, concentrated acetic acid would work quite fast.
"Special" Relativity, stupid ideas seem smarter when they come at you really fast.

Anyway, given time, even carbonic acid will dissolve limestone. That's the process that makes some caves.
