Thanks guys. I'll keep tinkering with this.. But for the meantime, til I have a breakthrough. Stick with coals.. I think that if one of those big Ecig companies got this.. Use the same technology that's in the cigs based on suction to put the burner on *draw, temperature. And then when there's no suction have an *idle, temperature then burning the shisha would be near impossible.. I might have gotten ahead of myself with this idea.. Needs more work.
