I love Luméjere, it's such a cool product. It is not a floating candle. It's a floating wick that sits on a thin layer of oil, on top of water.
The effect is that the fire is floating on the water. It makes for a very interesting wedding centerpiece. One that I'm sure your friends haven't seen yet! Find out more at their website
