Ok thanks for pointing out my faults AGAIN!
I know i'm not that clever but SOME stuff i know what i'm talking about... People only wave around the poloroids in the air will make them develop faster, which it theoreticallyshould as you are maximising the oxygen supply availablle for the silver nitrate to react with. The whole poloroithing was talking aboutthose impatient people... not people that can actually be bothered to wait! Lol
