The Smart Helmet is a helmet deigned to teach or be taught. When students go to school, all they have to do is put on the helmet, and the helmet will teach the students. It can also be set to a different mode where it can be taught. New information can be added to the helmet's memory, by people at work. Teachers wouldn't lose their jobs since there would still be people needed to make the helmets and sell them. This would be a revolutionary invention, and would make learning a lot of fun.
