If you’ve ever celebrated a birthday, you’re likely familiar with trick candles. These sneaky candles have a mind of their own and seem to keep relighting even after you blow them out.
Let’s explore the science behind these mischievous candles.
What are Trick Candles?
Trick candles, also known as magic candles, are a type of candle that relights itself after being blown out. These candles are typically used for novelty purposes, especially during birthday celebrations.
They can be found in various shapes and sizes and often come with other novelty features such as color-changing flames.
The Science Behind Trick Candles
The secret behind trick candles lies in the wick. Regular candles use a wick made of cotton or other similar materials that are treated with chemicals to help them burn more efficiently. Trick candles, on the other hand, use a wick made of magnesium.
When you blow out a trick candle, the magnesium in the wick remains hot enough to ignite the wax vapors that are still present in the air above the candle.
This causes a small flame to ignite, which then ignites the wick once again, creating the appearance that the candle has relit itself.
This process can happen multiple times, depending on the specific type of trick candle you’re using.

Types of Trick Candles
There are a few different types of trick candles available on the market. The most common type is the relighting candle, which relights itself after being blown out.
There are also spiral candles, which have a spiral-shaped wick that causes the flame to move in a spiral pattern as it burns.
Another popular type is the color-changing candle, which changes color as it burns. These candles typically use a chemical reaction to create the color change.
Some novelty candles even have specific shapes, such as letters or numbers, to spell out messages or ages.
While trick candles can be fun and entertaining, it’s important to use them safely. Never leave a burning candle unattended and keep them away from flammable materials.
Always blow out the candle before attempting to relight it and never touch the flame or hot wax.
Trick candles are a fun and unique addition to any celebration, but they are not just a simple gimmick. They rely on the science of combustion and the properties of magnesium to create their unique effect.
When used safely, they can provide hours of entertainment and enjoyment.
