This thread has been very helpful for me. I've wanted a proper commercial vape for ages, I just dont have the money. I made a light bulb vape a couple of months ago and WOW I think its the best way to smoke(well your not really smoking it, your inhaling the vapours). I noticed that the high was different from smoking from a pipe/bong/joint... it wasn't better or worse, just different. I heated the bulb too close to the neck and it cracked, then I cracked another bulb that I was using to make another one out of...I hav'nt bothered to make another one yet.
