A group of Ohio high school students learned the hard way how painful pepper spray can be. The teenagers were heard screaming in agony as the effects of the spray kicked in. The group of teens at Barberton High School willingly participated with their parents’ consent on how effective and potent pepper spray can be. “It’s like a volcano in my eyes!” one student shouted. The shocking video, shot by a parent, is causing a firestorm on social media. “Horrifying,” one person called it.
