You can grab the free Valentine Slime gift tags at the bottom of this post. We included 2 colors to choose from – pink and red so you can decide which color slime you’d want to make. Or you can make both! We also included a slime safety tag to glue to the back of the tags. This is important if you want to hand these out to other kids as not everyone is aware of slime safety.

Here is what the safety tip tag says:  Slime Safety Tips! This is homemade slime made with love using glue, baking soda and contact lens solution. If you are sensitive to these ingredients, please do not use. Slime is not to be placed in the mouth and you should wash your hands after use. Adult supervision is recommended.

Directions to Make Valentine Slime

We made two glitter glue slimes – this was the red slime.

And this is the pink slime.

Once you have both slimes made, you can fill your small mason jars. Depending on your size of jars you should be able to get 2-3 jars with one batch/recipe. We filled 2 small mason jars with one batch.

Now add your gift tags with a little bit of twine wrapped around the jar!

Steps for How to Make the Valentine Slime

1. Get a bowl to mix your slime ingredients in.

2. Pour your entire 6 oz Elmer’s Glitter glue into the bowl (or 3/4 cup of glue from a larger bottle).

We used red and pink Elmer’s glitter glue.

3. Add your 1/2 teaspoon of baking soda and mix in thoroughly.

Also add up to 1/4 cup of water if you want a more stretchy slime.

You can add extra glitter in too.

5. Slowly add in your contact lens solution (Reminder: your contact lens solution should contain boric acid or your slime will not form).

Add it in slowly and mix if possible so that you can adjust and ensure you do not add too much.

We like to add in 1 tablespoon to start and then mix. Then slowly add in the rest.

Knead and mix thoroughly before adding more as you do not want to add too much or your slime will get too hard.

You may not need the full amount so take this step slowly.

6.  Now mix until your slime forms and begins to harden.

Take it out and knead, knead, knead. You may be surprised how much you need to knead to really make the slime form. It will be very sticky at this point. Especially if you added water. Keep kneading and stretching the slime and it will become less sticky.

If it’s not the desirable consistency keep kneading. Only add a little more contact solution a teaspoon at a time to prevent the slime from becoming too hard.

If you still find it to still be too sticky, add a little bit of lotion or baby oil to your hands.
