Eddie - I'd be really careful about using something like this....

This is a class IIIb laser:
Lasers in this class may cause damage if the beam enters the eye directly. This generally applies to lasers powered from 5–500 mW. Lasers in this category can cause permanent eye damage with exposures of 1/100th of a second or less depending on the strength of the laser. A diffuse reflection is generally not hazardous but specular reflections can be just as dangerous as direct exposures. Protective eyewear is recommended when direct beam viewing of Class IIIb lasers may occur. Lasers at the high power end of this class may also present a fire hazard and can lightly burn skin.
Shooting them off a mirror ball isn't going to reduce the beam......you could seriously injure anyone......
But then again, wtf do I know?
Ask Randy - he's the engineering expert here. He'd be the one that could tell you how to do it and make it perfectly safe....
