Well Rayon is just another name for "man made cellulose", same for e-liquid, atomizers and mods, some a well made, some are just... garbage. You certainly have tried a Rayon that is either not pure, badly cleaned with chemical residues if chemically processed, or just not sterilized. I have not tried Rayon before the Fiber Freaks, so i can only assume. Still the "Rayon" made by FF is just of a top quality imho.
Well for this video i first wanted to show how quick, or how much liquid different material could absorb. Then i realized there is no point absorbing liquid if you can't deliver it back when solicited. I believe you got the wrong idea about all this and I feel very sorry my video sounded like i was a kind of expert or whatever, this was not the objective at all... Just tried to be informative... :/
I also mentioned in my video that the close-up experiment wasn't there to show evidence or prove anything, and this was the best way i found to just try and show the different densities of the materials on screen. It is to my opinion, better to show it that way than just vaping with it as vapour production is very hardware dependent.
I'm merely doing my thing here on this youtube channel, just trying to present/show/review new stuff coming out of France, again, not trying to prove anything... i'm a bit on the defensive there and i'm starting to think it was a bad idea sharing my videos on forums.
Anyway, I haven't seen busardo's demonstration but i'd be very interested in seeing that if you've got a link
