wow OK, I stand corrected. I always, wrongly assumed that more than tiny amount would make digestive system go crazy and probably cause vomit or other unpleasant consequences
To be fair, from my recollection of freshmen challenges, a cup of vinegar, a large raw onion, and a head of garlic is sufficient to either induce vomiting, or to compel the 'winner' to self-induce vomiting.
The advent of both these kind of challenges as well as Youtube have brought to light a level of durability of the human digestive tract I wouldn't have previously expected. One only needs to watch someone like skippy62able (L.A. Beast) to have their eyes opened (and possibly their gag reflex triggered). For example, witness him consuming baking soda and then drinking a glass of vinegar:

Vinegar has nothing on the natural stomach acid already present in your digestive system. People don't give enough credit to how resilient the human body actually is.
