A group of Barberton high school students agreed to be pepper sprayed for the purposes of education last week.
"Stop resisting, please comply", the instructor says in the video while discharging the chemical agent directly in the each student's face.
Each of the students who participated had to get their parents to sign-off on a waiver.
The form also reportedly noted that students would suffer "irritation and a burning sensation" in their eyes and nasal area for up to an hour after being sprayed.
In this Friday, May 12, 2017 photo provided by Melodie Steinhour, students at Barberton High School pose for a photo after getting pepper sprayed in Barberton, Ohio. It doesn't take long before the effects of the pepper spray - which has oleoresin capsicum, an oil found in very hot peppers, as its main ingredient - take hold. The students begin to cry out in pain, howling and waving their arms.
To those who have been in situations where one might expect to find themselves on the business end of a pepper spray bottle, the scene is familiar in some ways, but entirely alien in others.
If you were a student that did science while in high school, you would know that the experiments are one of the most interesting parts of being in the class.
"This is a controlled and safe experience for the students and is completely voluntary", the note concludes.
The video shows the students standing in a line, as one by one they are pepper sprayed; some of the students are seen screaming and jumping up and down.
The pepper spray training is meant to help students earn industry credentials in public safety from the Ohio Department of Education, the school said in a statement.
