The black spot on a metal spoon when held over a candle comes from the soot and carbon particles produced by the incomplete combustion of the candle's wick. As the flame burns, it releases tiny particles of carbon that adhere to the surface of the spoon, creating the black spot. This is similar to the way that soot is produced by other forms of incomplete combustion, such as from a car's exhaust or a wood-burning fire. **

When you pour carbon dioxide on a large candle and a small candle, the carbon dioxide will displace the oxygen around the candles. Since fire requires oxygen to burn, the lack of oxygen will cause the flames on both candles to be extinguished. This is because carbon dioxide is heavier than air and forms a layer that prevents oxygen from reaching the flames. **

After application, it is recommended to prevent the pet from licking the spot on treatment until it is fully absorbed. **
