robert42 Reviewed by robert42 on . VERY IMPORTANT QUESTION K, so started to make a lightbulb vaporizor.So I cut the metal screw part where you screw the bulb into sockets.And I gutted the bulb cleaned it out, nice and fresh.I got a cap that fits perfectly onto the metal screw.Well in the core of the metal screw/neck thing of the bulb theres green spongy stuff.I have no idea what it might be, I think it could be mold and im sure that wouldn't be healthy to inhale.Can anyone tell me what this is or what it does or how to get it out if its unsafe or what Rating: 5
