Can candles explode?

It is observed that the candles can really explode! This is due to a chemical reaction whereby water combined with certain types of fuel can cause combustion. This explosion is also called the candle fire. Therefore, in addition to following the safety measures, you need to keep your candles dry and away from water especially when they have a hot wax pool. As a result, you can identify the causes of wax fire and extinguish that easily. As per a study by the U.S. Consumer Product Safety Commission, 85 per cent of candle fires can be avoided by using three safety rules - never leave a burning candle unattended, never burn it near anything that can catch fire, and also keep the candles out of reach of small kids or pets. Similarly, opting to place candles in the glass jar is a bad idea as the same may impact the bottom and hence cause it to break and explode. The wax can fall out and thus cause a fire.
