Ingredients and Tools
To make glow-in-the-dark playdough, you'll need the following ingredients and tools:
- 1 cup of conditioner (preferably with a pleasant scent)
- 2 cups of cornstarch
- 2-oz. bottle of non-toxic glow-in-the-dark paint
- A large mixing bowl
The conditioner acts as a binding agent and provides a pleasant aroma, making the playdough enjoyable to use. Cornstarch is the primary ingredient that gives the playdough its malleable texture. When mixed with conditioner, it forms a dough that is easy to shape and mold. The non-toxic glow-in-the-dark paint is what makes the playdough glow in the dark, ensuring safe and fun playtime for children.
To make the playdough, simply combine the conditioner, cornstarch, and glow-in-the-dark paint in the large mixing bowl. Mix until you achieve a smooth, pliable dough. The playdough can be recharged by exposing it to light, allowing it to glow repeatedly. Store the playdough in an airtight container when not in use to maintain its texture and glowing properties.
Step-by-Step Instructions
Now that you have all the ingredients and tools, let's get started with the step-by-step instructions to create your glow-in-the-dark playdough.
- Mix Dry Ingredients: In a saucepan, combine 1 cup of flour, 1/2 cup of salt, 1 tablespoon of cream of tartar, and 2 tablespoons of glow pigment. You can choose either orange or purple glow pigment based on your preference.
- Add Wet Ingredients: Add 1 cup of water and 1 tablespoon of oil to the dry mixture. Stir everything together until well combined.
- Cook the Mixture: Place the saucepan over medium heat. Continue stirring until the dough starts to thicken and pulls away from the sides of the pan. This should take a few minutes.
- Cool and Knead the Dough: Once the dough has thickened, remove it from the heat and let it cool slightly. Transfer the dough onto parchment paper and knead it until it becomes smooth and pliable. This step ensures the playdough achieves the perfect consistency.
Now your glow-in-the-dark playdough is ready for use!
Helpful Tips

For a pleasant fragrance, blend in a few drops of inexpensive conditioner while kneading the dough. This addition enhances the playdough's scent and makes it feel softer. To optimize the glow effect, charge your glow-in-the-dark playdough under a light source before playing in the dark. If the glow diminishes, recharge it by holding the dough near a light source. Using a black light can intensify the glow, transforming playtime into a magical experience.
For a stronger luminous effect, use dark paint specifically designed for glowing, found in the acrylic paint section of most craft stores. Mixing this paint into your playdough ensures a bright, long-lasting glow.
If your playdough becomes too sticky, add a little more cornstarch until you achieve the right consistency. To add color without affecting the glow, use food coloring. It blends seamlessly into the dough, providing vivid hues while preserving the glow.

Storage and Maintenance

After crafting your glow-in-the-dark playdough, proper storage and maintenance are essential to keep it fresh and ready for future use. Store your playdough in an airtight container to prevent it from drying out and to maintain its consistency. Place the container in a cool, dry spot, away from direct sunlight, to protect its glow-in-the-dark properties.
Regularly inspect your playdough for any signs of mold growth. If you notice changes in texture or smell, discard the playdough and make a fresh batch using the original recipe. This ensures safety and hygiene, especially since children will be handling it.
If your playdough has dried out, you can refresh it by kneading in a small amount of oil. Add one teaspoon at a time until you achieve the desired consistency. This simple trick can extend the life of your playdough, keeping it as pliable as when you first made it. Proper storage and maintenance will ensure your glow-in-the-dark playdough remains fun and safe for future play sessions.
