Make your own soft, squishy glow in the dark clay with just a few simple ingredients! This easy homemade clay recipe is fun to shape, dries beautifully, and glows magically when the lights go out.
Add 1 cup baking soda, 1/2 cup cornstarch, and 3/4 cup water into a pan.
Turn the burner on medium heat and stir the ingredients to combine.
Continuously stir the liquid, scraping the bottom of the pan as you do so. Eventually you'll feel the mixture begin to thicken and it'll start sticking to your spoon.
Keep stirring the clay mixture. It will bubble up a lot as it thickens more.
Continue stirring until the clay mixture is thick like mashed potatoes and no longer liquid feeling (about 5 minutes).The clay will be quite hard to stir at this point. Remove from heat.
Step 3: Cool the clay
Spoon the clay onto a plate or baking sheet, smoothing it down into a thinner layer.
Cover with damp paper towel (or a tea towel) and allow to cool to room temperature before handling.This can take anywhere from 30 minutes to 1 hour, depending on the temperature of your room.
Step 4: Colour the clay (and make it glow in the dark!)
Divide the cooled clay into equal sized balls. We decided to make 6 colours of clay, so we separated the clay into 6 balls about 78 grams each. You can weigh the clay or just eyeball it -- it's up to you.
Flatten 1 ball of clay and set it on a baking tray or sheet of parchment paper. Then add 1/4 teaspoon glow in the dark pigment powder.The amount of pigment needed will depend on how much clay you're working with. 1/4 teaspoon worked well for our amount of clay.
Fold the clay around the pigment powder, then squish it together.
Continue kneading the clay until the colour is fully mixed in. Use the clay to pick up any stray pigment that's fallen on the tray.
Repeat to make the other colours of clay.
Now turn out the lights and see how the clay glows in the dark!
Step 5: Make things with your glow in the dark clay
You can roll out the clay and then use cookie cutters to create fun shapes.
You can also use your hands to sculpt things. Here we made a crescent moon shape, creating the curve by shaping it around a finger.
Or, if you want to make marbled/tie dye clay, you can do that too. Start by making "snakes" of each of the colours.
Push the clay snakes together into a log and then twist them around each other.
Fold the ends of the log in and then roll out the clay.
If you want to make a trinket dish, place a small bowl upside-down in the clay. Press down to make an impression and then use a craft knife to cut out the circle.
Place plastic wrap in the bowl and set the circle of clay on top, creating a rounded dish.
Once you've made your clay creations, set them on a parchment lined tray and cover them with a tea towel. This will slow the drying process, helping to prevent cracking.It will take at least 2 days for larger objects to dry. Flip them over after 24 hours to give the bottom a chance to dry as well.
Your glow in the dark clay creations are complete!
Now place them near a window or another light source and have fun seeing how they glow when the lights go out!
