Review on 12 Inch Air Horn Pump by Daniel Warren

I teach chemistry and physics in high school students and it's no wonder students sometimes fall asleep. I used to deal with it by calling her name, usually a few times, sometimes louder and louder until it sounded like I was mad at them for just hanging their heads down or going to sleep instead of doing something really serious do. It was solved with this beep. This adds a bit of a comical element, because when all the other students who are already awake see me taking it out, they put their hands over their ears and look at the sleeping student, expecting him or her to wake up. I'll add that if anyone else uses it for this purpose, seriously, keep a proper distance. I always try to be behind my podium and not in the middle of the class. Do not approach anyone using this attention-grabbing device as it is too loud to use in close proximity.
