Valentine’s Day Slime Recipe for Kids (Easy and Fun!)

Last Updated on January 6, 2026 by Allison Lancaster

Looking for a fun Valentine’s Day activity that actually keeps kids busy? This easy slime recipe is my go-to every February. My kids have made batches of this pink slime more times than I can count, and it never gets old.

This Valentine’s Day slime takes about 10 minutes to make and provides hours of entertainment. No complicated steps. No trips to specialty stores. Just simple ingredients you probably already have.

What You Need for Homemade Slime

Here’s what goes into this easy slime recipe:

• 1 bottle Elmer’s glitter glue (pink or red works great for valentines day slime)
• 1/4 cup warm water
• 1/2 teaspoon baking soda
• 1 tablespoon contact lens solution (must contain boric acid as a slime activator)
• Optional add-ins: heart confetti, fine glitter, red food coloring

Quick note on the contact lens solution: check the label for boric acid or sodium borate. These ingredients help the slime forms properly. I use the Target Sensitive Eyes brand and it works every time.

How to Make Valentine’s Day Slime

Grab a large bowl and let’s get started.

Step 1: Empty your glue into the bowl. If you want to make multiple batches of slime, just multiply the ingredients.

Step 2: Fill the empty glue bottle about 1/3 full with warm water (roughly 1/4 cup). Put the lid back on and shake it well to get all the remaining glue out. Pour this into your bowl and stir to combine.

Step 3: Add the baking soda and mix thoroughly.

Step 4: Now’s the time to add any extras like heart confetti, extra fine glitter, or red food coloring. Stir this all into the glue mixture before the next step.

Step 5: Add the contact lens solution and stir well. The slime will start pulling away from the sides of the bowl.

Step 6: Once the slime forms a ball, take it out and knead it with your hands for 2-3 minutes until you get the right consistency. If it’s too sticky, add a few more drops of the solution.

That’s it. Your pink slime is ready for play.

Valentine’s Day Activities with Slime

This valentines slime isn’t just fun to make. Here’s how we use it:

Sensory play: Younger kids love squishing it between their fingers. It’s great for sensory issues and keeps little hands busy.

Letter practice: Flatten the slime in a baggie and let kids trace letters with their fingers. Way more fun than worksheets.

Cookie cutter shapes: Roll it flat and use heart-shaped cookie cutters. My kids do this for hours.

Hide and seek: Press small toys or plastic hearts into the slime and let kids dig them out.

Party favor: Package small portions in cellophane bags with gift tags for a Valentine’s Day party. Kids love taking homemade slime home.

How to Store Valentine’s Day Slime

Store your slime in an airtight container or plastic containers with tight lids. It will last several weeks at room temperature.

Want it to last even longer? Pop it in the fridge. Refrigerated slime can stay good for about a month before it starts to dry out.

Label your container clearly. Trust me on this one.

Why This Slime Recipe Works

This is my favorite slime recipe because the contact solution method is reliable. Unlike recipes using liquid starch or borax powder mixed with water, this one is easier for younger kids to handle.

The glitter glue makes beautiful pink slime without any extra coloring, and the whole process is simple enough that older kids can do it mostly on their own (with adult supervision for the contact solution step).

How to Customize Homemade Slime

Want fluffy slime instead? Add 2-3 cups of shaving cream after the baking soda step for fluffy Valentine’s Day slime.

Prefer clear slime? Swap the glitter glue for a cup of clear glue and add your own glitter.

Going for red slime? Use white glue with red food coloring instead of pink glitter glue.

This Valentine slime recipe is a great way to spend time together before the holiday. My kids ask to make it every year, and honestly, it’s become one of our favorite Valentine’s Day activities.

Now go make some slime and enjoy the giggles!

Ingredients

• 1 (6 ounce) bottles Elmer's Glue in pink glitter
• About ½ cup warm water
• ½ teaspoon baking soda
• 1 tablespoon contact lens solution (containing boric acid), for each batch

Instructions

1. Empty the glue into a large bowl. 
2. Fill the empty glue bottle about ⅓ full with warm water (about ¼ cup) and seal with the lid. Shake well to combine the remaining glue with the water. Pour into the bowl with glue and stir to combine.
3. Add the baking soda to the glue and stir to mix thoroughly. 
4. If you are adding additional glitter, food coloring, scents, or confetti, stir into the glue mixture before adding the contact lens solution.
5. Add contact lens solution to the glue mixture and stir well. (Note: regular glue will require less contact lens solution than glitter glue. Add the contact lens solution slowly, mixing between additions, and add only enough to bring the glue together into a soft ball.)
6. Remove the slime from the bowl. The slime will be sticky. Begin to play with the slime, stretching or kneading it as you would bread dough, to bring the slime together. The slime is ready when it is no longer sticky.
7. Best if stored in an airtight container in the refrigerator when not in use.
