Vigorous stirring can produce air bubbles in your melted soy wax that can lead to imperfections in the finished candles. If you notice air bubbles, tap the container gently right after pouring to help any air bubbles escape to the top. Then, why did the smoke ignite while the candle without smoke did not? Here is his explanation: 1) When you are burning a candle, you are essentially vaporizing the liquid wax into a gas that is flammable. This vapor can then be used as fuel for the candle flame. 3) Therefore, as you hold a flame close to the smoke it will light the unused wax vapor that is in the smoke.

What happens if you touch a candle flame?

Burning is a chemical reaction. "Heating up" is a chemical process. When you swipe your finger through a candle flame, in order to feel pain, your hand has to warm up enough to trigger a neuron to send a pain signal to the brain.

Consequently, why do candles flicker?

The wick is drawing oil from the candle wax as fuel, and a buildup is created within the wick. If the flame gets too little or too much air or fuel, it can flicker or flare and unburned carbon particles (soot) will escape from the flame before they can fully combust. Which candle light goes off last Why? The candle that is the shortest will go out first.
