A Laser Projector
LCD projectors are mightily expensive, but they are absolutely necessary for teaching in the classroom. In an attempt to help gym students learn more about gym or something, this gym made the mistake of holding a book directly in front of the projector. As a result, the projector caught fire, causing the project’s lens to catch fire.
The principal was none too pleased after learning how much money would be required to correct this avoidable mistake. The tech support representative, on the other hand, was overjoyed! One school’s misery is a tech support officer’s source of happiness (and income).
