So, basically, I have been asked to prepare flavoured juice for a fog machine. I know some basic fog juice recipes, but I'm not sure what % flavourings to put in. Just as a test, we put ~.5ml of my banana cream juice (10% flavouring) in with about 100ml of the fog juice (vg/pg/water) that came with the machine; the flavour was very faint, but noticeable. I'm thinking of making 200ml, 70/30 pg/vg, no nic, with 1-5% total flavouring. This is not going to be vaped directly.

Does anybody have any experience with this, or have any ideas on this?

Edit: After I made this post, we did another test with 1ml of ejuice in 99ml of fog juice. Flavor was still barely noticeable, but the guy with the fog machine decided to try it this time in a more enclosed space. Nic was more noticeable in this instance than flavor (juice was 3mg). Pg taste was noticeable from whatever they use in the fog juice.

Conclusions so far: once again, no nic is going into the actual fog e-juice I make. I'm going to tell them to use this in a less enclosed space, and make sure that the fog has a way to escape. I'm going to keep with the idea of 1-5% total flavoring. The fog is pretty hot, so I'm going to mix with higher heat in mind.
