Valentine’s Day Play with Slime
The recipe for this Valentine slime uses one of our most basic slime recipes: clear glue or white glue, water, baking soda, and saline solution.
Now, if you don’t want to use saline solution, you can test out one of our other basic recipes using liquid starch or borax powder. We have tested all three recipes with equal success!
We added food coloring, glitter, and confetti hearts for a cute heart slime for Valentine’s Day. However, there are so many variations to try!
Why not come up with your own favorite Valentine slime:
- Try adding a cup of foam beads to the recipe for a floam slime. Make a batch in green and a batch in red. Use heart-shaped cookie cutters to make floam hearts.
- Try kneading in an ounce or two of soft clay after your slime is made for a butter slime. Make a batch in red and pink!
- Make it fluffy! Swirl fluffy slime in theme colors.
- Add all sorts of theme confetti and colored glitter.

How To Make Valentine Slime
STEP 1: Add 1/2 cup of clear Glue to your bowl and mix with 1/2 cup of water.

STEP 2: Add red food coloring, glitter, and red confetti hearts as desired.

STEP 3: Stir in 1/2 tsp baking soda.

STEP 4: Mix in 1 tbsp saline solution and stir until slime forms and pulls away from sides of the bowl. This is exactly how much you will need with the Target Sensitive Eyes brand, but other brands may differ slightly!
If your slime still feels too sticky, you may need a few more drops of saline solution. As I mentioned above, start by squirting a few drops of the solution onto your hands and kneading your slime longer. You can always add but you can’t take away.
NOTE: We have found that the Elmer’s specialty (glitter, color, glow) glues tend to be a bit stickier than their regular glue, and we prefer our 2 ingredient slime recipe for this glue.

STEP 5. Add some Valentine slime to small containers. Finish by adding our printable Valentine label to each Valentine.
