Make Jack Vomit (Or Cry)

BuzzFeed's own Jack Shepherd has boldly agreed to a Battle Of The Stomach Linings, in which he will consume as many different hot sauces, spices, and peppers as he can.

What should we make him eat? Help us come up with a list of the deadliest substances to force-feed Jack on camera, and hopefully things will turn out like this. (Note: Jack is a Vegan, so don't suggest pepper-crusted pig's tail or what have you).
