RR--Honesty, the end of my wick hasn't reached the exit yet, so I'm not sure what it'll do when it does! A guess...since the wick is fed through the oil first, it gets saturated with it. Because oil and water don't mix, the water doesn't saturate what has already been saturated, if you get my meaning. Again, that's just a guess!! 

Glad you like the project.

Nice project. It takes the "make a candle out of a wine bottle" one step closer to elegance. One question though: The wick reaches fairly low into the bottle where the water is. Won't it soak with water too?

I knew there was a reason I was saving all those wine bottles.

Wonderful!  I have been saving an odd-shaped wine bottle for some time now.

I imagine this could easily be adapted to make citronella candles in the summer?

very cool! - thanks for sharing

P.S. That line you see in the bottle is actually where the water and the lamp oil meet; they don't mix. Looks really cool.
