Valentine’s Day Confetti Slime with Saline Solution

We first made saline solution slime in our Silver and Gold Glitter Slime. It was such a great slime that we wanted to make more. We have another valentine slime recipe – our 2 ingredient glitter slime is perfect for Valentine’s Day. It’s made with Elmer’s glitter glue and liquid starch.

Today we’re making a new batch of valentine slime with saline solution as the slime activator instead of liquid starch. You want to make sure your saline solution contains boric acid and sodium borate. (I use Up & Up Saline Solution from Target.) Contact lens solution also works as a slime activator but you’ll need a different amount. Saline solution seems to work better and it costs less. The boric acid and sodium borate react with the PVA in the glue to create a polymer. A polymer is a long chain of similar molecules all connected together. This is what forms your slime and makes it stretchy.

I recommend using Elmer’s transparent glue for this recipe. You don’t need liquid watercolors, paint, or food coloring. Extra thumbs up for the glue being washable. Feel free to substitute clear glue and your choice of coloring. I like washable liquid watercolors.

In addition to the saline solution and glue, you’ll need baking soda and water. The baking soda helps to thicken your slime. The amount of water you use in your slime also changes its consistency. More water causes the slime to flow more. It’s more goopy. Less water creates a thicker slime. Try different amounts of water and see which version you like best. We like slime pretty much any way.

Safety note: Always supervise the making and playing of slime. Once finished wash your hands to get rid of any residue (ingredients can dry skin). Slime should only be used with kids that won’t eat it. While the ingredients I use are technically non-toxic and safe for everyone to handle (assuming you’re not allergic), it’s not good practice to allow kids to eat slime. Too much could cause an upset stomach. The saline solution itself should also not be ingested. Seek medical attention if this occurs. Other slime recipes have different ingredients so be sure you understand the safety requirements before using those. For a taste safe version of slime, try making oobleck.

Ingredients Needed for the Saline Solution Slime Recipe

  • 1/2 cup of Elmer’s pink transparent glue (pretty much the entire 5 ounce bottle or as much as you can get out)
  • 1/2 cup of water (or 1/4 cup of water if you want a thicker slime)
  • 1/2 teaspoon of baking soda
  • glitter (CraftProjectIdeas.com always keeps us well stocked in glitter.)
  • heart confetti (I found our heart confetti at Hobby Lobby.)
  • 1 tablespoon of saline solution

Instructions for Making Valentine’s Day Slime


Pour the Elmer’s transparent glue into your bowl. Squeeze as much out of the bottle as you can. It will be about 1/2 cup. Add up to 1/2 cup of water. You can rinse out the bottle of glue if you want. Experiment with the amount of water you add each time you make a different batch of slime. See which slime consistency you prefer. I like a thinner slime for this batch because of all the glitter and confetti we’re adding.

Use a craft stick or spoon for stirring slime. Once the water is completely mixed into the glue, add 1/2 teaspoon of baking soda and stir.

Now it’s time to add the glitter and heart confetti. I added 3 different colors of glitter – a fine pink glitter, red glitter, and a larger purplish pink glitter. (You can really only see the purplish pink glitter.) You can also add the glitter and confetti at the end once your slime is formed.

Next you’ll add the saline solution. You’ll need about 1 tablespoon. You could start with a little less if you’re worried about your slime being too brittle. Add the saline solution and stir quickly to combine. The slime will be sticky at first. Keep stirring until it pulls away from the container.

Lastly, it’s time to knead the slime. Add a few drops of saline solution to your hands before you pick up the slime. This will keep the slime from sticking to you.

Knead the slime until its the consistency you like. If it’s still a bit sticky, add a drop or two of the saline solution and knead some more.

If you make the slime just right, it won’t stick to your hands. You might want to wash your hands of any remaining glue and then play with your slime. It’ll be nice and stretchy.

Does your slime have enough glitter and confetti? If not, add some more!

We also made purple glitter slime with Elmer’s purple transparent glue. I just love the color of this slime. The glitter shimmers so wonderfully.
