My wife and I usually enjoy our evenings with a glass of red wine. We often light some candles and relax on the sofa. Last night, while we were watching the Paralympic opening ceremonies, I noticed a "tail" on one of the burning candles.
This looks like an unusual wax bead. Perhaps it is wax which was closer to the wick and melted during the earlier part of the candle burning, and then flowed over the edge, down the side of the candle. Now that it is farther from the wick, it seems to sit just below its melting point. Any other ideas?
