With the Vaporstar you can easily turn your glass bong into a high quality vaporizer.

The Vaporstar is very easy to use. A butane gas flame is drawn through the Vaporstar using he power of the lungs, which heats up a small steel star contained within the extraction chamber. From the star sixteen points of heat surround and penetrate the herb, driving the temperature upwards until vapour is seen in the glassware.

It will fit any small glass pipe for tabletop use (separately available), and fits 14.5 mm fitting or the 10 mm rubber collar fitting.
