Not much originality to it, but I happened to get some new tank parts in and I had them setting out new to my new Vortex cartomisers. The idea had to happen sooner or later, so I made what I think Ill call Tornado tanks. Its a very simple, tried and true method. I took two rubber grommets, a mouth piece off of a regular cartomiser, the left over tube of a metal ce2, (though I could have cut the stock plastic one, I think it would look really nice with all clear parts).
