Curious person here with a warning: don’t smell 30% vinegar. You are missing nothing gods by skipping this. I promise.
At least I’m curious now..
People have been avoiding learning the smell and taste of several kinds of poison with a great amount of success for thousands of years. Be one of the successful ones.
Anyway, I don't think anybody ever tested that, because that will hurt your nose before you get the chance to drink it.
You may find after a few tries that it smells just like the split second before vomiting.
