VALENTINE’S DAY SLIME

Learning how to make fluffy Valentine’s Day slime is much simpler than you might think. Slime making is even more fun when you add in creative themes for special occasions days like Valentine’s Day. This fluffy slime is perfectly festive for this time of the year! We love simple Valentine’s Day science activities!

 We have several slime ideas to share, and we are always adding more. Our Valentine’s Day Fluffy Slime Recipe is yet another AMAZING slime recipe we can show you how to make.

Oh, and slime is science, too, so don’t miss the great information on the science behind this easy slime below. Watch our awesome slime videos and see how easy it is to make the best slime!

Do you know we also do science experiments and STEM activities for kids and science experiments for preschoolers too?

BASIC SLIME RECIPES 

All of our holiday, seasonal, and everyday slimes use one of five basic slime recipes that are super easy to make! We make slime all the time, and these have become our go-to favorite slime recipes!

Here, we use our Saline Solution Slime recipe. Slime with saline solution is one of our favorite sensory play recipes!  We make it ALL the time because it is so quick and easy to whip up. Four simple ingredients {one is water} are all you need. Add color, glitter, and sequins, and then you are done!

Where do I buy saline solution?

We pick up our saline solution in the grocery store! You can also find it on Amazon, Walmart, Target, and your pharmacy. You can not make a homemade saline solution for slime.

Now if you don’t want to use saline solution, you can absolutely test out one of our other basic recipes using liquid starch or borax powder. We have tested all these recipes with equal success!

NOTE: We have found that Elmer’s specialty glues tend to be a bit stickier than Elmer’s regular clear or white glue, and so for this type of glue, we always prefer our 2 ingredient basic glitter slime recipe.

HOST A SLIME MAKING PARTY AT HOME OR SCHOOL!

I always thought slime was too difficult to make, but then I tried it! Now we are hooked on it. Grab some saline solution and PVA glue and get started! We have even made slime with a small group of kids for a slime party. This Valentine’s Day fluffy slime recipe below also makes a great slime to use in the classroom or to give as Valentine’s gifts.

SLIME SCIENCE

We always like to include a bit of homemade slime science around here! Slime is an excellent chemistry demonstration, and kids love it too! Mixtures, substances, polymers, cross-linking, states of matter, elasticity, and viscosity are just a few of the science concepts that can be explored with homemade slime!

What’s slime science all about? The borate ions in the slime activators (sodium borate, borax powder, or boric acid) mix with the PVA (polyvinyl acetate) glue and form this cool stretchy substance. This is called cross-linking!

The glue is a polymer and is made up of long, repeating, and identical strands or molecules. These molecules with flow past one another keep the glue liquid. Until…

You add the borate ions to the mixture,  and it then starts to connect these long strands together. They begin to tangle and mix until the substance is less like the liquid you started with and thicker and rubbery like slime! Slime is a polymer.

Picture the difference between wet spaghetti and leftover spaghetti the next day. As the slime forms, the tangled molecule strands are much like a clump of spaghetti!

Is slime a liquid or solid?

We call it a non-Newtonian fluid because it’s a little bit of both! Experiment with making the slime more or less viscous with varying amounts of foam beads. Can you change the density?

Did you know that slime aligns with the Next Generation Science Standards (NGSS)?

It does, and you can use slime making to explore states of matter and its interactions. Find out more below…

FLUFFY VALENTINE’S DAY SLIME RECIPE

No shaving cream handy? No worries, make our regular Valentine’s Day slime instead.

We made three batches of our Valentines Day fluffy slime so we could swirl them together which is always tons of fun! Plus, you get one big fluffy mound of slime to play with, too.

Since one can of foam shaving cream will make four batches of this fluffy slime, have some fun picking out your colors. One really important thing to note, you will need extra food coloring for deeper shades of the colors.

Make Valentines Day Fluffy Slime Recipe with Shaving Cream, Saline Solution, and GluePin

YOU WILL NEED:

  • 1/2 cup White PVA School Glue
  • 1 tablespoon saline solution (must contain boric acid and sodium borate)
  • 1/2 cup of water
  • 1/4-1/2 tsp baking soda
  • 3 cups shaving foam
  • Red food coloring

HOW TO MAKE FLUFFY SLIME:

STEP 1:  Add 3 cups of heaped shaving foam to a large bowl.

STEP 2: Now’s the time to add food coloring and slowly mix it so you don’t lose the fluffiness.\

We went for a pink/ red fluffy slime for our Valentine’s Day theme!

STEP 3: Add 1/2 cup water and 1/2 cup of glue and combine completely.

STEP 4: Stir in 1/4- 1/2 tsp baking soda.

Baking soda helps to firm and form the slime. You can play around with how much you add but we prefer between 1/4 and 1/2 tsp per batch. I get asked all the time why do you need baking soda for slime. Baking soda helps to improve the firmness of the slime. You can experiment with your own ratios!

STEP 5: 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. Saline solution is preferred over contact solution.

STEP 6:  Start kneading your slime! It will appear stringy at first but just work it around with your hands and you will notice the consistency changes. You can also put it in a clean container and set it aside for 3 minutes, and you will also notice the change in consistency!

SLIME TIP:   We always recommend kneading your slime well after mixing. Kneading the slime really helps to improve its consistency. The trick with this slime is to put a few drops of the saline soluti9n onto your hands before picking up the slime.

You can knead the slime in the bowl before you pick it up as well. This slime is stretchy but can be stickier. However, keep in mind that although adding more activator (saline solution) reduces the stickiness, and it will eventually create a stiffer slime.

You will love how easy and stretchy this Valentine’s Day slime is to make, and play with too! Once you have your desired slime consistency, it’s time to have fun! How big of a stretch can you get without the slime breaking?

STRETCHY SLIME vs. STICKY SLIME 

Which slime is the stretchiest? This slime recipe is by far my favorite slime recipe for stretchy slime!

A stickier slime will be a stretchier slime, no doubt. A less sticky slime will be a firmer slime. However, not everyone loves sticky slime! As you continue to knead the slime, the stickiness will lessen.

Tinkering with the baking soda and saline amounts will change the consistency of the slime to thinner or thicker. Keep in mind that any recipe will come out just a bit different on any given day. This is a great chemistry experiment, and one of the things you will learn is that slime is meant to be stretched slowly.

SLIME FAILURES

The biggest reason for slime fails is not reading through the recipe! People contact me all the time with: “Why didn’t this work?”

Most of the time, the answer has been a lack of attention to supplies needed, reading the recipe, and measuring the ingredients! So give it a try and do let me know if you need some help. On a very rare occasion, I have gotten an old batch of glue, and there is no fixing that!

STORING YOUR SLIME

I get a lot of questions regarding how I store my slime. Usually, we use a reusable container, either plastic or glass. If you keep your slime clean, it will last for several weeks. And…if you forget to store your slime in a container, it does last a few days uncovered. If the top gets crusty fold it into itself.

If you want to send kids home with a bit of slime from a camp, party, or classroom project, I would suggest packages of reusable containers from the dollar store. For large groups, we have used condiment containers as seen here. We also have printable Valentine’s Day slime labels you can grab here!

*NOTE: Fluffy Slime doesn’t keep like our other basic slime recipes due to the nature of shaving cream!

Our pink or magenta fluffy slime was the best color!

Our red fluffy slime fell a little short in the color department but still fun none the less. We added cookie cutters and little heart containers to our Valentines day fluffy slime for extra play!

I had hoped for a darker purple, but this is still a pretty shade to add to the other colors of fluffy slime! Luckily when the shades are all similar, they don’t mix into an icky brown color.

Fluffy slime colors stay separated for much longer then the regular slime colors! So we had a ton of fun stretching, twisting, and mixing before they all swirled together.

  4. Hi,

    The actual recipe doesn’t seem to have shaving foam included. Should the shaving cream be used instead of water?

  5. Add the shaving cream first, and then follow the recipe as normal. Thanks for picking that up!
