New vaper here. I was trying to figure out an easy way to test juices in small amounts. I have an RDA on the way which seems to be the canonical answer. Still gotta clean it and change the wicks between flavors. So far I have been putting enough in a tank to wick properly, testing, then decanting/disassembling/cleaning/drying/refilling. That is Teh Suck. Since the RDA isn't here I put a small drip/drib of juice on an aluminum foil square and heated it gently from below with a torch style lighter. This seemed to work rather well and had the benefit of letting me breath in through my nose and mouth separately. Obviously it won't be exactly the same as vaping on an atty, but even attys vary between them. Seems to me the critical part is heating gently with a sweeping flame to avoid overheating. Is this already a thing and I'm just not finding it in my forum/web searches? Is it called something else? Is it deprecated because it looks shady?
