I just saw this on youtube and am wondering if anyone else uses this flavor testing technique ?
this guy set out a few clean cups, he added 1:1 flavors, 1 drop each flavor to a small pipette of water in a cup ... he put the mix in his mouth, swished it around and spit it out (no, he did not swallow it) ... took a sip of tea, he is a Brit, then ate a small piece of bread
next clean cup, he tried a 2:1 ratio, went through the same palate cleansing scenario ... after about 7 tries he ended up with a 3 flavor recipe he liked ... his final mix was 4 drops, 2 drops, 1 drop ... then he increased the ratios for a 30 ml bottle, along with his nicotine and vg base
it was kind of funny to watch it, but I realized these are food flavorings and I don't think he's hurting himself ... it certainly saves nicotine and flavorings and wicks and coils and eliminates the hassle of actually vaping every little test mix
do you think this is harmful ? anyone else do this ? ... or what is your testing technique ?
