---you tell a friend/classmate to just lick the pepper juice off his/her fingers and then laugh! (My fifteen-year-old son did this in his high school class when they were studying fermentation and were making kemchi. He took some overripe habs to school to use for the experiment. We made a certificate for one of the boys in his class that ate a whole habanero on a dare, and still maintained a relatively normal respiration rate!)
