At first glance, I was head over heels when I saw Dan's initial post, but now that I've slept on it, I think it'd need to be majorly tweaked to run perfectly. For starters, I think very small slits or perforations on the part of the pyrex that your coil goes on would do wonders for the flow dynamics, and it would also help to heatup the
juice quite a bit faster. It's a fascinating idea and definitely something to continue exploring in the future! Cloud, when you get your tubing, please shoot me a PM as I'd love to pick your brains on how it's performing and possibly
buy a small amount from you to do some trials of my own.
