Alright. I confess, I’ve never actually performed the experiment and I am merely assuming what the results would be. Nevertheless, outside of the occasional Disney animation, I’ve never seen any candle anywhere cling to, well, anything.
This may have something to do with candles being inanimate objects, but like I say, I haven’t done the experiement. Maybe if left in the rain, candles really do cling. (Of course, you’d have to perform your tests with at least two candles, since the song fails to specify at any point whether the candle is lit or not.)
