How to take apart a laser pointer. Hope this helps!
If you can't get yours working, may I suggest this set of lasers: https://amzn.to/2LVoJEq (Amazon)

Note that Amazon link is affiliate, meaning I get a small cut of that or other items you buy withing a set amount of time at no additional cost to you. Also, I haven't tried those lasers, but they look very similar to what's in the video.
