The Bubble Vaporizer
The Bubble is similar to vaporizers you can build yourself.
It's quite simple in design and does work, but it's not the most efficient vaporizer possible.
It's best to use a candle as the heat source as it will use a lot of butane if you use a lighter.
If you rotate the glass a lot, it can be quite a good method of vaporization. It is vaporization at it's most basic, however.
If your looking for a cheap method of vaporization and don't mind a little work, the bubble could be for you!
