A candle snuffer is a tool used to extinguish candles safely and effectively. It typically consists of a small bell-shaped cup attached to a handle. When the cup is placed over the candle flame, it cuts off the oxygen supply, causing the flame to go out without producing smoke or splatter. Using a candle snuffer is often preferred over blowing out a candle, as it helps prevent wax from splashing and reduces the risk of soot buildup on the candle's wick. This tool is commonly found in homes, especially where candles are used for ambiance or aromatherapy.
