In one sentence, describe what the following article is about:

Pour the water in first. Then add the contents of both Kool-Aid packets. Use a spoon to stir them together until thoroughly combined.  Choose Kool-Aid that has powder the color that you want your pubic hair to be. For example, cherry Kool-Aid will result in red hair. You can also mix packets for different colors. Place the saucepan on the stove and bring the water and Kool-Aid to a boil. Stir it while it boils so the powder doesn’t settle at the bottom. On a stove with 9 heat settings, medium-high heat is 6 or 7. Don’t leave the mixture in the hot pan or it will continue to cook, which can affect the strength of the color. Transfer it to a bowl immediately.  A cup or basin will work if you don’t have a bowl. If you use a plastic container, the Kool-Aid could stain it. Dip the brush into the bowl to soak up the liquid. Then brush it over your hair, making sure to coat every strand with color. Avoid putting the Kool-Aid mixture on super sensitive spots of your pubic area.  Do this over an old towel if you don’t want to get Kool-Aid stains on the floor. You can buy a hair color applicator brush at a beauty store or from an online retailer. You can also use a paintbrush with soft bristles instead. Lighter hair, like blonde or gray, will absorb the color faster. However, darker brown or black hair will take at least the full 30 minutes to change color. To keep track of the time, use your phone’s clock app or set a timer. Run water over your pubic hair to remove the Kool-Aid. Gently scrub the area with a washcloth, too, to get rid of any extra color that may be on your skin.  Once the water runs clear, all of the Kool-Aid mixture is gone. If you want a deeper color, repeat the entire process once your pubic hair dries. The color will last for 2 to 4 weeks, depending on how often you shower.

Summary:
Mix 2 packets of Kool-Aid with 2 cups (470 ml) of water in a saucepan. Boil the liquid for 1 to 2 minutes over medium-high heat. Remove the pan from the heat and pour the liquid into a bowl. Use a hair applicator brush to apply the mixture to your pubic hair. Let the Kool-Aid mixture sit on your pubic hair for 15-30 minutes. Rinse the mixture off of your pubic hair with warm water and a washcloth.
