Well. Your laser will only burn a few things, and black/dark material is needed to absorb the light/heat.
A 50mW pointer should be able to burn through a thin Black plastic bag in about a second, and Black electrical tape in about 5-10 seconds (depending on thickness).
If you want to light matches with it, you need a lens (like a magnifying glass) to focus the beam, and you also need to color the match with a black felt-tip pen so it will absorb the laser light. And, if your laser is anything less than 50mW, you will also need a lot of patience and a very steady hand to light a match. :can:
Lol Ash I know you were just so excited you wanted to show that! Cool Pic!!!
Btw Try to search, theres like 3 threads about a 50mw laser going around. It's easy to use
As I recommended in the other threads you may be interested in our CNI group buy (we place a large order at a factory and get discounted prices). The guy organizing this Group buy bought a few 50mw lasers last time and they were actually 100mw!!! Check out the thread in the group buy section
