My niece is in charge of a workshop at a youth camp and wants to set up a laser obstacle course, similar to what you see in movies for security systems. I told her I would help her, so I am hoping this is possible, not too hard, and not too expensive. I figured it could be done with some laser pointers and mirrors. I have a fog machine to hopefully make the laser beams visible. Will this work? Any suggestions on how to do it and what lasers to use? Thanks for any help you can give!
