vodka soak test

[emu]

I read somewhere that they cause molecular disruption in coils and release trace particles of metal, which then end up in your vape. Jury is out, but whenever possible I err on the side of caution and due diligence...

Thanks that'll save me some hard earned money.

Calling fab, brother LNB has my hopes up now.

I did a random soak test on a few subjects, here's some of the results:

drinking it i dont know

crystal head 50 ml is 15 bucks

I'm in the Philippines atm. 200ml Smirnoff for 5 bucks 😇

Ah... so it is good vodka. You should be right.

I never attempted drinking it after... it ends up looking a bit like bong water...

Like you've never drank bong water? 😅

How much is shipping for around 2L of Smirnoff from there?

I was in Thailand last year. Same adorable prices. You could get it at 7-11. Wasn't the real deal in the bottles though...

Fab will know, blokes a right genius, he will forget more than all of us will ever know...

I think it's highly unlikely there is any "molecular disruption". Ultrasound does not work on frequencies that can disrupt molecular bonds - if ultrasound could break ionic bonds in molecules we'd all have way more problems than what our coils were doing. Think of other even higher frequency things that obviously do not cause molecules to break apart - microwave ovens, medical ultrasounds, x-ray machines, your mobile phone, radio transmitters...

Molecules are so small that it requires very high frequencies to just rip them apart - like gamma rays for example. Now that's nasty stuff, and there's a reason it's call ionising radiation.

Ultrasonic cleaners just physically remove weakly bonded molecules - crud caked on a coil, grease in your atomiser, or the odd persistent flavour molecules that you want to get out of your atty.

Anything that ultrasound can break off, was already going to break off at some point anyway. Ultrasound just speeds the process up while it's in the bath, that's all.

Thanks for clarifying. I was fairly certain back when I read it that essentially shaking the shit out of something can't really destroy it at a molecular level... but given I got into RTA I didn't extend myself to actually researching the claim.

Watch any decent submarine movie, and they'll go on about 'cavitation', which is very much what ultrasonic cleaners are doing.

Cavitation happens when you have a low pressure area on a moving 'thing' in a liquid. It causes a small gas bubble, and when that gas bubble collapses it's like hitting the surface with a small hammer. Boat propellers are often chewed up not by corrosion or small creatures or impact damage, but by cavitation when the prop is spinning too fast to bite the water properly, you get low pressure on the 'front' side and it's like tapping away with a heap of small hammers until bits chip off and the prop gets 'eaten'. Death by a thousand cuts.

Ultrasonic cleaners pass waves through the liquid (water usually), and any small imperfection in the surface causes a small low pressure area (like the prop) and a small gas bubble to form and collapse. If that imperfection is contamination, it's likely not well held and should break off. As Fab says, if it breaks off, it would have broken off somehow anyway. These small bubble actually 'hit' with a huge force relative to their size, but they're really small so the actual forces are small. Just a lot of them constantly. Kind of like sand-blasting or media-blasting. Lots of little hits = a lot of work done.

I hope that kind of explains things, and why they won't be breaking down metal molecules. They may actually break down a coil or atty, but you'd need to have a particularly aggressive 'cleaner' and leave it in there for a very long time.

There's always a doom sayer for anything you can dream up. Sometimes they're right. Sometimes they're accepted in public because they've managed to stop making messes on the floor and and aren't excessively offensive to the eyes or nose...
