It actually works, but you have turn the focus power by rotating the top. I did it on Geepas 303 laser If there is sunlight, its more better to burn the stick.
yeah bro I have tried just now by zooming my 303 lazer and 6 cm distance between lazer and matchstick only in few seconds it started burning really amazing 😍🤩
The lens focus can get adjusted also the real threat from lasers are temporary to permanent blindness as it takes a while for it to actually burn something and the human hand is considerably hard to burn using a laser and green is around the second most absorbed colour out of the three main red, green and blue being the wavelength that the human eye is most sensitive to out of them. Red would be even harder for you to burn as the light gets scattered by your hand(This also explains why pulse laser used for treatments are often red. Blue would probably be the best even then it’s not even a real threat to your hands.
