Let me jump in here, too....
Katnik is talking about the little bottles of imitation flavoring found in the baking section by the spices....not a cake mix.
You cannot put just anything in your PV and expect it to vape. It's the PG/VG in the PV that produces the vapor when heated....that's part of its chemical property.
If you try to put a regular juice or soda pop in your PV, you're going to ruin the attomizer. even IF you can get it to produce a vapor (doubtful without the PG or VG) its going to taste nasty (like burnt soda or juice) and you will either burn out or gunk up your atty.
If you want to mix your own juices - buy some loranns flavorings

*Note: do not buy any flavorings that are oil based*
some Proplyne Glycol (PG) - you can ask for it at your pharmacy.
and some glycerine(VG) you can get this in the cake-decorating supplies of most craft stores.
2 to 1 PG to VG - add your flavorings, and thin the mix with a bit of distilled water if its too thick.
That will give you a wealth of flavor combinations without the nic and without major damage to your atty.
