Your cheapest/best bet would be to use a lighter.. but if you must use a laser, do as yobresal suggests. Be aware that using a high-powered laser around a glass or metal "tobacco" bowl is a recipe for disaster since a tiny reflection at those power levels will cause permanent damage if it should happen to find it's way into your eye. Lighters are a tad less blinding.
It would be really hard to light the tobacco with a 200mw laser, I think it would just burn the tobacco instead
Alright I am looking for a portable laser pointer that could easily light a bowl filled with tobacco of course. I dont care if its green, red or blue and im not trying to spend a fortune. Anyone got any ideas
Why i'm encouraging you I have no idea but....
