It is 100% effective There are 2 ways you sleep during class. Either you kiss the desk or you comfortably lean back on your chair. My invention solves the problem in both of these scenarios flawlessly. We have tried this method and out of the 0 dummies we tested on, 100% of them didn't report getting injured. "This method is a new and exceptionally good way of disciplined training so then our children could stay up and learn in class," says Mr. BlueGuy, a kindergarten teacher at Bluegood Elementary, "My students always fall asleep during class, and after I set up this magnificent device on each of my students desks, they never slept in my classroom ever again." This new installation could be life changing as our children will finally get a chance to learn at school and not just dreaming of what they'll learn. Futher interviewing from Mr. BlueGuy backs up this theory. "I believe that this is a ginormous hit and should be in every school in the world." Don't take anything up there seriously.
