Re: has anyone ever tried or heard of this?
Not that I'm a hookah expert but this may work. If you guys have ever used an e-cig it is the same concept. Flavored juice with glycerin is heated up and produces smoke and flavor in e-cigs. The difference between this and an e-cig is that they add nicotine to smoke "healthier" persay. This is the same concept but without the nicotine being added. Now there are other things in the juice but the overall concept is the same. The liquid would evaporate over time but you could still get a session out of it I think.
This seems like a pheasable idea and should at least be explored before being discounted.
