Everybody gets frustrated at work. It can come because of your ding dong coworkers, stupid bosses, idiot customers...the list is endless.
These teachers got a chance to let it all out with The Screaming Machine, and the meter inside even shows how loud they're getting. I have a few teacher friends and I know that they'd love to have this in their schools. Heck, every business should have The Screaming Machine because there are fools everywhere!
