This Valentine’s Day slime recipe is the perfect craft to add a festive touch to your day. It’s easy to make, uses simple ingredients, and provides hours of sensory play.

Ingredients to make Love Day Slime Recipe
- 2 cups of white school glue
- 2 teaspoons of borax
- Food coloring (red, pink, or any Valentine’s color you love)
- 2 ½ cups of boiling water
- 2 mixing bowls
Instructions
Step 1: Prepare Your Glue Mixture
- Start by boiling around 3 cups of water. You’ll need this for the recipe.
- In one bowl, mix 2 cups of white school glue with 1 ½ cups of boiling water.
- Add a few drops of food coloring to your glue mixture. Red or pink works perfectly for a Valentine’s theme. Stir with a spatula to combine thoroughly.
Step 2: Create the Activator Solution
- Combine three teaspoons of borax in a separate bowl with 1 cup of boiling water.
- Stir the mixture well until the borax is fully dissolved.
Step 3: Combine the Mixtures
- Slowly pour the glue mixture into the borax activator mixture.
- Stir the combined mixture gently with a spoon. You’ll notice the slime forming as the glue absorbs the activator.

Step 4: Get Hands-On
- Once the water has cooled down slightly, mix the slime with your hands.
- Use your palms to squeeze, stretch, and knead the slime. This helps it absorb any excess liquid.
- Continue stretching and kneading until you achieve the perfect slime consistency.
This Valentine’s Day Slime Recipe recipe is awesome because it is less stretchy and slimy than store-bought slime, which makes it easier to handle and less messy. And we can all use a bit of less messy activities right?!
Step 5: Time to Play!
Once all the liquid has been absorbed, your Valentine’s Day slime is ready to enjoy! Add glitter, heart-shaped confetti, or tiny sequins for extra festive flair. Store it in an airtight container when not in use to keep it fresh.

- Safe Play: Supervise younger children during play and remind them that slime is not edible.

Create Valentine’s Day Slime that Crunchs!
This year, we decided to change our slime tradition; from mixing pink and white slime, we created a crunchy Valentine’s Day Slime Recipe.

To make crunchy slime you need styrofoam beads. For Valentin’es Day we chose red and smaller purple ones, but you can recreate this idea for any ocassion! we had made birthday themed one with rainbow colored beads!
Make it a learning activity
Slime is great to work on fine motor skills. Squeezing, pulling and stretching will help your child strengthen their fingers, wrists and hand muscles.
But, adding non-sharp scissors, can be a great scissor activity to work on learning how to use scissors and understanding how siccors cut before giving them paper.
