A man sends pepper gas in the face of volunteer students. On May 12, 2017 in Barberton, Ohio, students in the criminal sciences agreed to be sprayed with the face of pepper gas. Some will soon regret the choice. Aligned standing against a wall, the students were sprinkled with pepper gas a few inches from their face. After a few seconds, you can hear cries from several teenagers who are writhing in pain. The pepper gas used by the riot police has a value between 2 000 000 and 5 300 000 on the Scoville scale. The world's strongest chili, the Carolina Reaper, is located between 1 569 300 and 2 200 000.
