Talk:Secret Agent Laser Obstacle Chess/@comment-29141199-20160814065046

it really is just a spray bottle.. lysol and floating aerosol should do the trick the thing is its a lot easier to see since the thing is on camera. with the naked eye you can still see it but the camera picks up a lot more light than the naked eye can catch. it really isnt that defined when you do it. the same can be accomplished with a laser pen and a cigarette blow smoke passed the laser.
