Trick candles, also known as magic candles, are novelty candles that can relight themselves after being blown out. They work by igniting magnesium inserted into the wick, which then sets alight the paraffin vapour given off when the candle is blown out. While they are currently legal in the US, they have been banned in Canada since 1977 due to the fire risk they pose. This is because consumers may throw them into the trash believing them to be extinguished, only for the candles to relight and start a fire. Experts caution against the dangers of trick candles, recommending that they are thoroughly extinguished by immersing them in water before disposal.

How do trick candles work?
Trick candles, also known as magic candles, are a fun addition to any party. They are novelty candles that can relight themselves after being blown out. But how do they work?
Firstly, it is important to understand how normal candles work. When a regular candle is blown out, there is a burning ember in the wick that causes a ribbon of paraffin smoke to rise from the wick. This ember is hot enough to vaporize the paraffin but not hot enough to ignite the paraffin vapour.
Trick candles are made from the same wax as regular candles, typically paraffin hydrocarbons. However, the wick is where the difference lies. In a trick candle, the wick contains magnesium powder. Magnesium is a highly reactive metal, especially when powdered or sliced thinly. It can ignite at temperatures as low as 800 ºF (430 ºC).
When you blow out a trick candle, the hot embers from the wick ignite the magnesium powder, producing tiny sparks. These sparks then set alight the paraffin vapour, allowing the candle to relight itself. This process can repeat itself multiple times, creating a fun and surprising effect.
While trick candles are entertaining, they also present a fire risk. People may accidentally throw them in the trash, believing them to be extinguished, only for the candles to relight and start a fire. Due to this hazard, trick candles were banned in Canada in 1977. To safely dispose of trick candles, it is recommended to immerse them in water for a while before discarding them.

Why are trick candles dangerous?
Trick candles, also known as magic candles, are novelty candles that can relight themselves after being blown out. They work by incorporating magnesium powder into the candle's wick. Magnesium is a highly reactive metal when powdered or sliced thinly, igniting at temperatures as low as 800 ºF (430 ºC). When a trick candle is blown out, the hot embers from the wick ignite the magnesium powder, producing tiny sparks, which then ignite the paraffin vapour and relight the candle.
The danger of trick candles lies in this ability to relight themselves. People may believe that the candle is extinguished after blowing it out, leading them to dispose of it in the trash. However, the candle can reignite due to the heat of the embers, potentially starting a fire. This risk is heightened if the candles are thrown away immediately after being blown out, as the embers may still be hot enough to ignite the magnesium and subsequently the paraffin vapour.
To mitigate this risk, it is recommended to thoroughly extinguish trick candles before disposal. This can be done by snuffing out the flame, dunking the candle in water, or running it under water to deprive it of oxygen and prevent reignition. It is advised to wait for a period of time, such as an hour or two, to ensure the candle remains extinguished before discarding it.
Due to the fire hazard they pose, trick candles have been banned in Canada since 1977. However, they remain legal in other countries, such as the United States, where a complete ban may be challenging due to various product safety concerns taking precedence. Instead, the focus is on educating consumers about the potential dangers of trick candles and the importance of proper extinguishing techniques.

How to extinguish trick candles?
Trick candles, also known as magic candles, are a fun addition to any birthday party or celebration. They are so-called because they relight themselves after being blown out. This is achieved by inserting magnesium into the wick of the candle. When the flame is blown out, the hot embers from the wick ignite the magnesium, which then ignites the paraffin vapour and relights the candle.
Due to the risk of fire, it is important to know how to extinguish trick candles properly. Here are some methods to do so:
- One way to extinguish a trick candle is to use a candle snuffer. This is a metal tool that has been used for centuries to extinguish candles. Place the bell of the snuffer, the small cup at the end of the long handle, over the wick. This will deprive the flame of oxygen, stifling it gradually. Candle snuffers create minimal smoke and soot, making them a cleaner alternative to blowing out the candle.
- Another method is to blow out the candle. To do this effectively, position your face close to the flame, with the wick at around mouth level. Purse your lips together and then blow, exhaling suddenly to create a thin stream of air. Keep blowing until the flame is completely extinguished. Be careful not to blow too forcefully, as this can cause hot wax to spray and result in a mess or minor burns.
- To ensure that trick candles do not relight themselves after disposal, it is recommended to run them under water before discarding them. This will extinguish any remaining embers and prevent the candle from reigniting. Barbara Miller, a spokeswoman for the National Candle Association, suggests letting the candles sit in water for an hour or two before putting them in the trash.
It is important to note that trick candles pose a potential fire hazard. They have been banned in Canada since 1977 due to the risk of unsuspecting individuals discarding hot trick candles and accidentally starting fires. Always exercise caution when handling trick candles and ensure they are completely cool before disposal.

There is no mention of trick candles being banned in any other place besides Canada. In fact, they are currently legal in the United States, where they are commonly manufactured in Asia. However, experts like Barbara Miller, a spokeswoman for the National Candle Association, have expressed concern over the potential fire hazards associated with trick candles. She recommends educating consumers about the dangers and taking precautions, such as immersing the candles in water before discarding them.

Are there alternatives to trick candles?
Trick candles, also known as magic candles, are a fun addition to any party. They repeatedly reignite due to the presence of magnesium powder in the wick, which is shielded from oxygen and cooled by liquid paraffin when the candle is burning. However, they can pose a fire hazard as people may dispose of them prematurely, believing them to be extinguished. As a result, they have been banned in Canada since 1977.
If you are concerned about the potential dangers of trick candles, there are alternative ways to bring fragrance and ambiance to your home or party. Here are some options:
- Reed diffusers: These offer a longer-lasting alternative to scented candles, with a 6-ounce reed diffuser providing fragrance for up to 4 months, and a 15-ounce reed diffuser lasting up to a year. The reeds soak up the fragrance oil through capillary action and disperse it into the air.
- Candle warmers: These are ideal for small to medium-sized candles and can be used to create a warm and inviting atmosphere.
- Essential oil diffusers: These are a great option if you like to create your own fragrance blends or change scents based on your mood. You can also purchase smart diffusers that allow you to create a custom fragrance experience with the touch of a button or through a smartphone app.
- Fragrant flowers: Fresh flowers not only add a touch of beauty to your space but also provide a natural fragrance. Depending on the season, you can choose from a variety of scented flowers such as roses, lilies, gardenias, or sweet peas.
- Aromatic herbs: Herbs like basil, mint, and lavender not only have culinary uses but can also fill your home with a pleasant aroma. Place them near an open window or door to allow the scent to waft inside.
- Incense: Incense sticks and cones have been used for centuries to create a calming and relaxing atmosphere. They come in a variety of scents and can be found in many specialty stores.
While these alternatives may not have the same relighting surprise as trick candles, they offer safer and more sustainable ways to enjoy fragrances and create a cozy ambiance.
