After watching many videos on youtube of people burning things with high power lasers, I wanted one.Those lasers can cost a lot of money though, something I don't have. So I made one, and in this instructable, I will show you how to make one for less than ten bucks. This is my first instructable, so if I did something wrong, please tell me. This laser outputs between 50-100 milliwatts(I think), and can burn electrical tape, light matches and melt thin plastic.I was messing around with this laser one day, and I shined it at a mirror, and the laser shined back in my eye for a second. I heard a popping sound and I couldn't see anything for a couple of minutes. Now, I was LUCKY that I did not get permanently blinded, but if I shined it a second longer I probably would have been. Now with that said, NEVER point a laser at another person, animals, or any other living thing.
Okay, Now lets make the laser.
