At the risk of sounding like an idiot, which Im obviously not very afraid of... What's the point of the experiment? To see if we can jam more cotton in a coil in an effort to achieve the same results as we're getting now? Why? Most, if not all of us have worked for a long time to get to the point where we have success with our wicking... whether that be in tanks or drippers. More wicking isn't necessarily a good thing....the correct amount is always a good thing. We've all over wicked and got dry hits. We've all underwicked and got spit back followed by a horrible metal taste. How can jamming a ridiculous amount of cotton in a coil be called an experiment? Most of us have already done it but back then, we called it either the 'Scottish Roll' if it worked or we called it a 'Mistake' if it didn't.
I'm lost here....

Hi Asbestos! Take a look at this video. It might clear things up a bit 
Real life heat experiment this time, almost sciency Remember to dial down watt with 20% or add another wrap or two to the coil if you use mech mods. And wick as hard as the coil can handle. Consider spaced coils to make sure, by inspection, you don't get new hotspots.
All reports on other forums shows that these results are valid in real life, even for RDTAs (which I know nothing about.) It looks like those who disagree have not tried it. A common reaction btw

DISCLAIMER: I have not watched the videos.
I think the biggest thing being missed here is that Jurin's Law pertains more toward how high a liquid can be moved by capillary action and if we were trying to wick to a mountain top it would be more applicable. What we are concerned with is capillary speed. How fast can than wick move the liquid across the required distance to keep up with the evaporation rate? Thus any formula you use MUST have a time component and if you want to make sure the capillary speed is greater than the evaporation rate you would also need to account for surface area, temperature, etc. A more compacted wick will be able to move liquid higher (against gravity) but not necessarily faster (or even fast enough to keep up with the evaporation rate).

I agree for the most part.
Read this before you watch the third video:
I have done aditional experiments after the video. The distance from the bottom of your well to the top of your coil is critical. Here is my Law of Fluffing: 1. Never fluff, you just destroy the fibres. 2. If the distance is less than 11mm, spread the ends slightly. 3. For distances between 11-15mm, leave the cotton alone. 4. For distances more than 15mm, press or roll your cotton wick ends gently together. 5. Do your own experiment, with the wicking material you use. These numbers are for organic Japanese cotton pads bought in bulk, and only valid for me. Go make your own law

I watched the entire video. It had the vibe of one of those ASMR videos that continue to freak me out.
I'll give you an A for effort. But I'm not sure the experiment actually proves anything. Perhaps its just over my head. Regardless, I think I'll stick with what works perfectly for me. However, I appreciate the amount of time and effort you put into the video.

It does not prove anything, as stated in the video, but you asked what this project was good for. And the answer is more vape, better flavor, much less spatter and saving energy. For me. As stated in the video. But thanks for appreciating the work I put into this
I'm not forcing anyone to do anything, just giving informed choises on experimental basis. And sorry for the ASMR. English is not my first language, so I have to think before I say something
It was a million times better than me doing a video in Dutch! Great English and a cool beard.

I think this is pretty much Where I am Also.
Going with what works Best for Me. But appreciate the Time Spent and the Scientific Approach seen in the Video.
Yes - very nice videos. Thanks for doing them!
My thoughts go to the video showing the center of the wicks saturating first.
IMO, having the exterior of the wick is of primary importance to offer liquid to the coil.
It seems the tightness of the wick through the hole constricts the liquid flow.
However, your 2nd video does show better results for your vaping style/system etc.
And as mentioned, in RTAs, the legs of the wick - as in amount in the juice channel, seems to be a greater variable from one tank to another and getting the best vape.

Thanks! And as you hear in the video, I agree. But if the juice never gets to the coil due to distance, that is not good either. You have to make the experiment for your self, with your own wicking material and your own distance. I know nothing about RTAs or RDTAs, but those who use the latter report much better results now in other forums. But who knows what they did before this
And your mentioned PBrusardos videos, so you may have seen this, but it was an interesting test on different wicking materials: a couple of frame grabs I took and annotated ->

Maybe I will....you know, if what your saying is true, then all dry hits from any tank has to be from the tails either being to long, to bushy, or perhaps to short, because it is well documented that something is to much, causing dry hits....once people get these dry hits, it is usually fixed by pulling out a few strands from wick. So I guess it could be they have fixed the problem, because they reduced the volume in tails? All one knows by this, is that it worked, whether it worked because they reduced the amount in coil or reduced the amount in tails is interesting....yes in an rta, like the kayfuns, which I have been vaping for years, I know for a fact you can have to much wicking material, because I have tested various amounts and when to much is added, it just doesn't wick, and you will get dry hits, period...now maybe it is because of the extra packed coil, has an extra large tail, which is just to much in the channels? Maybe I will try to pack the tar out of a coil, but reduce the tails to a normal size, to see ....if that is the case, then that would have to be tested against just a normal wick job, to see how they compare? It may not be worth it in the end

Morton, I watched your second video and I like the results, but not to suprised. For one, when you stated as much as possible, I imagined you twisting the cotton completely into a twisted thin rod, then untwisting once in coil...we use to do this year's ago, but now, people just twist the very tip and thread thru. If one doesn't completely twist the cotton, and just thread it through with maybe just holding the coil, I agree, you probably cannot overstuff coil....except for the last 2 test strips you had, I would of never thought people would use such tiny amounts of cotton thru a 3.5mm coil, especially at those wattages, and am not surprised that those particular people are getting much better results....I don't vape drippers and even cotton, so am not familiar with whatever the norm is, but it does seem that there was perhaps a trend in the last couple years to not twist and go really loose, and if so, I definitely agree on your results. ..when I use to use cotton, I believe I was cutting a 7mm strip of ... cotton for a 2 or 2.5 mm coil , while trimming tails slightly and never had issues.....
Question, when you inserted the thickest test piece in your coil, did you twist and roll with your fingers, so it was a dense rod before threading through and then straighten it out after? I ask because I once tested a few wicks and by far, the dry hits came from coils that had not enough, rather then to much, it wasn't until I twisted and rolled a massive piece dense piece, that I was able to get a dry hit.....as said before, there is another factor in rta's, and that is the channels, where in some, you cannot use to much, at least in there....
