Really, don't know nor can say if it's a troll post or not, can also be true ..... especially considering all the peoples that buy chinese "100mW" and "200mW" pens on street markets, without know a damn hell about what really is a laser and how it must (and overall, how it must not) be used, just cause it's a "thin beautiful light beam" that can be used for point objects and do jokes with friends ..... damn them .....
Once, at a marriage banquet, 4 or 5 of the husband friends was shining the faces of the two with red keychains pointers, thinking it was "funny" ..... luckily, with 2 mW red pointers, but still a stupid thing to do ..... so, after few minutes, it started to upset me, i took out my old, faithful 65mW green pen, hide rear a corner, and started to shine at them (never in face, ofcourse, only flashing at the hands that hold the pointers) ..... they stopped very quickly (LOL, 2mW of red against 65mW of green ..... no history
)
