I remember when I was in 5th grade and we were going to get our pictures taken and we had to fill out a card which had a choice of backgrounds; well one of them was "lasers" so I thought "oh great, I can ask the technician all sorts of questions about how they work and, ... ect". To say the least I was sorely disappointed when I realized it was only a picture of lasers on canvas that I would be standing in front of.
