How did VG as a solvent work for you? Does it come out of solution once cooled?
Other than lethicin, it looks good. I'd probably add more AVB though - I usually use double the amount of AVB than fresh material
When I make caps I usually make larger batches (100+ or so) and was looking into making something similar out of wood. Filling them manually takes a while, but damn for $30 I'll probably order what you linked
You're right, the vapor produced by whatever substance isn't visible. The vapor, intially hot, cools down and condenses the water molecules in it and around it, but it's not very dense so it floats. It technically is a cloud!
I love how simple AVB edibles are. I've never added it to oatmeal, but I love putting a couple grams in yogurt with grains. It masks the taste and texture!
