This is actually prop related, im almost finished with this lighter from a latenight Japanese television series "GARO", and it is a modified zippo lighter with a special effect of a green flame that is used for detecting what are basically demons. Anyway my question is, is there any way a zippo can be modified ro emit a green flame? Ive thought of just using green flame butane torch lighters, but none of them resemble the inside body of a zippo, is there any kind of special lighter fluid that can do this? Am I nuts?
