rollinKansas Reviewed by rollinKansas on . Is Aluminum Foil bad? Is aluminum foil bad even if you only use it like twice a month tops? i always use some aluminum foil for a nice gravity bong but never on custom pipes. I was wondering if it would be bad to put it on a homemade bong and use it as the bowl or should i find a better bowl? Rating: 5
