Does it matter? If the heat from a bic made my fairly thick vodka bottle vape explode (It was really cool looking too), no telling what a Sobe will do. Look at the top for the sticky on lightbulbs, and look for the "How to make a safe lighbulb vape" thread. As for the ashes,
1. Don't suck so hard (not an insult lol)
2. Don't push your straw that far into the lightbulb.

PS. You joined on my B-day :jointsmile:
