Its fairly easy to build a zipper coil. Got a drill and some 28g Kanthal? Take 2 strands of kanthal and twist them together with the drill until you have 2 completely twisted together kanthal wires. Next do the same thing again with another two strands but this time going in the oppositte direction with the drill (i.e. pulling a screw out rather than drilling it in). Then just do a parallel coil build with each of your twisted wires (5-6 wraps can give usually between 0.17-0.21Ω) and youve got a zipper coil. If you did it right the two wires will look like a little zipper. This funnels juice into those little channels for maximizing flavor, even being a sub ohm build. This is not a very safe coil build for many batteries due to the incredibly low sub ohm rating, but if you know your batteries limits an ohms law youll be fine. I dunno if theres any vids of how to make em out there but if you can figure out twisting the wires correctly theres definitely vids on parallel coils so its not too complicated. With dual zipper coils i literally obscure my entire face and torso upon exhale. Should look like this...
