This is a really cool activity!
You take a laser pointer and tape it to the wall on the end of a long narrow hallway. Then position CDs (the mirror sides facing towards the beam) along the wall so that the laser points to one CD and then ricochets off of that, and then points to the next CD, then the beam bounces off of that and so on and so forth.
Then you need to turn on a fog machine which picks up the laser beams.
You can time each kid as they crawl through the laser beam obstacle hallway one at a time from one end of the hall and back. The kids need to avoid the laser beams and not get "hit" by them!
