That is excellent, good statement to support your lasers for responsible kids only theory. Lets educate those kids by letting them watch us shine a 500mW green laser at a white piece of paper. I would assume that you would give them all glasses, or just have them stare at the spot?
All I can say is I'm glad that you don't have a 500mW green laser. Blinding a bunch of schoolkids would really be great for the laser world.
And CAM, lookie here! Just random thread where another user says how crappy his rayfoss laser is. Just FYI, a decent 100mW laser will light a match. Your laser probably is not even 100mW.
