The Vapo-bowl has a standard thread, so it can be attached to all kinds of pipes and bongs, turning them into effective vaporizers. You can easily change the temperature inside the bowl by adjusting the screen position.

Usage
Keep a butane gas flame above the entrance of the Vapo-bowl and start inhaling. A stream of very hot air will now flow through the herbs inside the extraction chamber, taking along the vapours that are released. When you remove the flame, the air in the Vapo-bowl will cool down and the vaporization stops.
