so they have these gummy bears with a shitton of capsaican, like 9,000,000 scovilles or something. you're supposed to chew them for 5 minutes, and they say it's like getting maced in the mouth. maybe a 6/10 of pain or something, it's intense but it's over fast. also you can make it easier with milk, that'd probably drop it down to a 4/10 or something. But 5 minutes and it's over.

if you want a pain russian roulette, use those.
