Laser protests

It's a nice sentiment, but things haven't exactly worked out for the pro-democracy movement in HK.

Am I the only one thinking about the possible eye damage from all that random laser flying around? But maybe these pens don't have enough power to require eye protection.

If you cover it in a glow in the dark material, preferably something that glows bright for a relatively short period of time, people could make drawings on it.

In my experience, the blue (405nm) lasers pointers can far, far exceed the nominal (5mW?) power.

I was able to burn a piece of paper once by taking a laser pointer and using a magnifying glass to focus it onto a black part of the paper.

I’ve seen glasses or caps you can buy that use infrared. I believe some cameras can have a filter to block it though. But add LEDs too.

In the US the police would shoot on the first laser fired.
