One of the questions we get quite often from our customers is regarding floating candles, or rather candles that float. The question is usually along the lines of ” What makes the candle float or Will any candle float?” There is a pretty consistent look of surprise when we explain to them that just about all candles will “float”. (I say “just about” since I’m sure somewhere there is a candle that won’t) It is not the shape or size of the candle that makes it float but the fact that wax is lighter than water. The shape of a floating candle is important since that determines if the wick will stay out of the water. You could put one of our biggest pillar candles, 6×9, in a tub of water and it will float, only it will float on its side, putting the wicks under water.
