This thing is soooo dangerous!! I feel we should not say words to encourage or "glorify" such things.. (in case people or kids especially gets tempted to try it) .. Not all forum-ers are responsible thinking adults who knows the danger of laser..
Just my 2 cents~

man, i've got tons of these diodes lying around... let me go see.. from what i know they're pretty harmless, i dont see how it can light a flame since the lens is made of plastic..
ohh.. they are dvd burner diodes... ahh.. i just tried it with a cdrom diode and putting 3v on it seems to have cooked the diode. the diode's turnon voltage is 1.3v, putting 3v on it got it really hot.. but no light no sound.
