Anyone else do this? Layering the juice in the cart? I often do it when I top off an almost empty cart. Maybe 3 drops menthol, then 3 drops raspberry mint, and then either a few more menthol drops, or maybe something like creme de menthe. But you can do whatever flavor layers you want. The juice stays in the layers, and I can definitely tell when I've hit the next one. It's kind of nice to get the different flavors without having to drip, or change carts.
I haven't tried it when filling a new cart, since I doubt it would work as well, but like I said, it works great when topping off. I imagine the PTB wick greatly helps keep the layers separate.
