Vacuum pop

[Spazmelda]

I don't know what to call this, but I heard someone call it a vacuum pop, and thought that sounded good.

A couple of coils I've made on the kayfun, I will get this. It's like a bubble that builds up as current is going through the coil. It builds and then pops. The coil I'm using now does not do this, and even if a coil does it's not terrible. I guess I get used to it or just rebuild.

Anyway, what exactly is happening here? It doesn't seem like a physical liquid bubble (no bubble or popping sensation if the button is not pressed). I don't think it's a hot spot, because my coil glowed nicely from the middle out when I checked it.

Um, more info... 30 gauge kanthal 6-7 wraps, maybe 1.6-1.7 ohms, touching coils, cotton wick, provari at 4.3ish volts.

I think it comes from the wick and coil being completely saturated. I only get those deep pops when I'm getting some great vapor.

I think what you're describing is the sound of juice cooking really well, that sound is music to my ears!

i think that its the sound of crusted juice on the coil getting vaporized. when the coil is warm, i typically dont hear it. but when i fire the device after a period of inactivity, i do (on certain atomizers- happened a lot with ribbon kanthal in my igo-L). i believe its cooled or perhaps even crusted juice on the coil. once that cooled/crusted juice heats up itll pop. but then subsequent vapes will not have the pop because the juice and coil hasnt completely cooled off yet.

It's the sound of an amazing vape.

Well, this was happening with a brand new coil, and was every vape. Then, dry burned it and it still had the pop.

I'm thinking there must be different pops. Lol.

Maybe you found the golden ratio of coil wraps/wire thickness/inner diameter. With the setup I'm currently using, I get way better vapor with my current wraps than I did with one less wrap. With the extra wrap I got more vapor and more flavor. Vaping is all about heating a coil and spreading that heat out the best way. Maybe you found one of the best.

Ha, it was my very first rba coil. I guess should have used it longer instead of ripping it out to build another.

I get what you're experiencing all the time and on brand new coils. I also got this less frequently on some genny style RTA's and when I fired the mod with the cap off to check it out, this was alway juice exploding off the coil (very cool little juice frag grenade-type pops).

In my KF attys, it doesn't seem to undermine either the vape quality or coil longevity.

Yeah, the vape was still fine. Good to know it just seems to be something that happens occasionally.

I've experienced the Bang Snaps poping on some new twisted coils with saturated virgin cotton wick. Not really fun. Once broken in the sound turned into that awesome frying bacon sound.

I figured it was mini steam explosions from super heated liquid that didn't have a clear steam vent path.

This sounds like a plausible explanation. I usually get the Vacuum Pop followed by the sizzling bacon sound, if I don't I tinker with the coils until I do.

Some of the pops were so violent I was a little stunned. I could feel the shock waves and feel the pressure wave. No scalding hot ball of fire shot into mouth so I'm good.

That's how my 24g dragon sounds. It's like I'm making a tiny skillet of fajitas in my igoL with the sizzles lol

I get better performance from coils that run pretty quiet.

I like the sizzle sound w/o the pops.

I think the pop is the wick catching on fire. It sucks up all the air then goes out.
