    cant seemt to get that sweet-ness in my juice

    Maybe it lacks "spice"? Like acetylpyrazine, linalool, vanilla or salt. What we perceive as sweet in more "industrialized juices" is usually a combination of these + sweetner.

    "Girls with dreams don't smoke or vape" - teaching our children to be prejudiced

    The motto "I saved $$$ by not smoking" together with a new "I saved $$$ by not buying metal tubes, batteries and hygroscopic concoctions" would be be a better approach in campaign for youth. More money left for other "social status" apparatus, like a new cool car, or for more effective...

    I'll be advanced in no time!

    Really? I was fiddling with the steam engine calculator to arrive at 3 wraps at 2.5mm per strand. Glad to see I was wrong, english not my first language. :D But anyway, glowing usually means the coil isn't cooling from vaporization of the liquid. So it needs more contact with the wick (more...

    Help, please. Getting discouraged

    A lot of tank systems rely on a gravity/pressure vs liquid viscosity equilibrium to not flood and leak. Draw patterns can stress that equilibrium pretty easy. I've switch ~3 months ago and someone described perfectly what happens before a leak: the "furiously sucking" draw technique that you...

    How often to rebuild coils?

    How do you guys rewick without deforming the coil? Every time I try to pull a gunked cotton wick, my coil decompress, spiralling gets uneven diameters and I end up rebuilding.

    According to steam engine coil wrapping predictor you're sub-ohming at 0.3 ohms. :ohmy: Quite bold for a first build. I never crossed the 1.3 limit even on a tridet. Coil wrapping | Steam Engine | free vaping calculators Double check your battery specs, it's at the range where it could go wrong.

    SM V3 Semovar VS Provari

    ~~ Intermission for thermal runaway paranoia ~~ Is it normal for a battery to get warm during use? I'm using efest and panasonic and sometimes I notice the battery tube to get warm (not hot). I'm running kayfun with 1.5ohms micro-horizontal-cottom at 7-11 watts (depending how my wicks decide to...

    New study - number of people who have tried e-cigs levels off

    Gotta love the hearsay and suggestions. Some people dislike the "blogtization" of media, but I like this idea that when everyone, including big media, is just blogging... nobody should look for authority in opinion. Also have you people noticed the slideshow beneath the article talking about...

    I'm battling some ANTZ from Cali with edits to the wikipedia page on e-cigs

    That is why I mentioned the social-economic aspects. I use consensus in the abstract taking into account the repeatability of experiments and the lack of "truth". But repeating (varying, publishing and "marketing") experiments require money, so it is prone to power play and being a double-edged...

    I'm battling some ANTZ from Cali with edits to the wikipedia page on e-cigs

    Well guys, consensus is how the scientific method works. There are no "truths" in science, only hypothesis that survive experiments (until they don't). You people might end up shooting yourselves in the foot if you continue with this edit war "for the truth". What I understood from the talk page...

    Semovar/Provari/Tube MODs USB passthrough?

    Is there any product that would plug-in into an usb port on one end and tread into a "18650-like apv" simulating a battery? This isn't about these devices having a usb port for passthrough, but rather a part that "is a battery when plugged" as far as the chips (or even a mechanical mod) are...

    Jut seen this....NY

    I don't think we should dismiss the pyrolisis regiment (I use dry burn for when there is absolutely no juice in the coil) experiments. Badly designed coils (given air and heat flow) could marginally increase pyrolisis because of hot spots. What a marginally increased pyrolisis would feel to the...

    The Dangers of E-Cigarettes: Toxic Metals Exposed

    It's all about what significant means. Heating metal and eroding it with air increases the levels. Does is reach a significant level in a drag? Does it increase lung tissues(and plasma) levels in 1 day of chain vaping? Does it increase in 1 week? 1 year? 10 years? Is it enough to impact public...

    The Dangers of E-Cigarettes: Toxic Metals Exposed

    From first principles of physics, it's not a surprise: all substances theoretically exist in nature in the 3 phases. This doesn't change for the materials in an atomizer. Temperature only changes the quantities. For example, palladium takes a long time to have an observable change in mass if...

    The Dangers of E-Cigarettes: Toxic Metals Exposed

    Doesn't this also happen when you cook food? Funnily enough, the first hit I got on google while researching for this is a company that ends the article with "stop cooking,and let us cook for you with our super duper cookware".

    Thin-Layer Chromatography

    Here is a video demonstrating the technique: https://www.youtube.com/watch?v=w0FyQ_tO15U The visualization step there can be tonned down to UV lamp + marking. The problems I describe have to do with organic solvents, specially apolar ones, usually being hazardarous to handle, so there is a...

    Thin-Layer Chromatography

    Has anybody done any TLC on net for analysis? We could even make an atlas for (ballpark) comparision. The difficulty here is that for home lab environment, and safety, we would be doing static organic with moving polar process. Organic layer, in a kitchen environment, could be too inconsistent...

    How many years WERE you a analog smoker?

    I started smoking at 22-24. Hard to point out exactly when I "started". I did experiment drags way before that but never succeed in getting any high/sickness. Might have been passive smoking from family and friends since very young, giving me a higher resistance to nicotine. I seriously never...

    Ethanol Extract - Full Strong Buzz & Moderate flavor

    How hard(expensive) is it really to do vaccum step/fractional distillation on the extract? Edit: From eye sighting phase diagrams, this naive process wouldn't be accurate, but for the kind of precision we are aiming here (specially regarding the crude stuff) it could work. Edit 2: Yeah, I was...
