[quote author=nvmextc link=1229024166/0#4 date=1229035299]if its a BR its fun to get the back of peoples necks when they are on the computer, they keep swatting like a fly and dont know what it is. ;D
I only done that a couple times with a close m8 of mine that I build lasers with, when he is to preoccupied to turn around, driving games etc. I wouldn't do that if I thought I could blind someone :-/
Some proper things I've burnt.
I engraved my safety boots with 90mW 780nm. That looked cool cos after a week or two it was white writing on the black boots.
Can light cigarettes with 135mW BR just as good as 210mW red!
That BR just about burns everything I try though, my walls, my computer desk, white electrical tape which was surprising.
Yer, can't think of much else more atm.
