The Experiment

The Gryffindor candle experiment is a fun and easy activity that involves using a regular white candle, a red crayon, and a yellow crayon. To begin, you will need to light the white candle and let it burn for a few minutes until a small pool of wax forms at the top. Once this is done, take the red crayon and hold it over the flame, allowing the wax to melt and drip down onto the candle. This process can be repeated with the yellow crayon, adding another layer of color to the candle. As the wax from the crayons drips onto the candle, it will slowly start to blend and create the iconic red and gold Gryffindor colors that are recognizable to any Harry Potter fan. Overall, this experiment is a great way to get creative and add a touch of magic to your home decor.

The Science Behind It

The color-changing candle operates on the principle of capillary action, which is a phenomenon where a liquid is able to move through narrow spaces without the need for external forces such as gravity. In the case of this experiment, the wax extracted from the crayons travels up the wick of the candle via capillary action. As the wax heats up and liquefies, it drips onto the candle and merges with the molten wax already present, resulting in a blend of colors.

Capillary action, the scientific process at play in this color-changing candle, refers to the ability of a liquid to travel through tight spaces without the aid of external forces like gravity. In this particular experiment, the wax sourced from the crayons is drawn upward through the wick of the candle due to capillary action. Once the wax liquifies and flows onto the candle, it combines with the existing melted wax, leading to the creation of a unique hue.

The intricate mechanism behind the color-changing candle is attributed to capillary action, where a liquid can move through narrow spaces independently of external forces, such as gravity. During the experiment, the wax derived from the crayons is pulled up the wick of the candle through capillary action. When the wax reaches the candle and melts, it blends with the molten wax on the surface, resulting in a vibrant new color.

Recreating the Gryffindor Candle at Home

If you are interested in creating your own version of this enchanting candle in the comfort of your own home, there are a few essential supplies that you will need to gather before getting started. To begin with, you will require a white candle that has a thick wick. Alternatively, if you prefer, you may opt to use a white taper candle for this project. Additionally, you will need to have red and yellow crayons on hand in order to achieve the desired color effect for your candle. If you happen to have candle wax dye available, that can also be used as a suitable alternative. Lastly, do not forget to have a lighter or some matches close by, as you will need them to ignite the candle once you have finished creating it.

Tips for Success

For optimal results when creating your color-changing candle, it is highly recommended to use a white candle that possesses a thick wick. The thickness of the wick enables a greater amount of wax to be drawn up, resulting in a more vivid and vibrant color when melted. To further enhance your candle-making experience, feel free to explore various colors and combinations to formulate your very own custom color-changing candle. Moreover, when incorporating crayons or wax into your candle design, it is important to hold the chosen material over the flame for a few moments to ensure proper melting before carefully dripping it onto the surface of the candle.

Safety Precautions

As with any experiment involving fire, it’s important to take safety precautions. Make sure to have adult supervision if children are participating in this experiment. Also, be careful when holding the crayon or wax over the flame to avoid getting burned. And always remember to never leave a burning candle unattended.


The Gryffindor candle experiment is a fun and easy way to bring a little bit of magic into your home. By understanding the science behind it, you can recreate this color-changing candle at home and impress your friends and family. So grab your supplies and get ready to channel your inner Gryffindor with this fun experiment.
