This lucky leprechaun got to make a fresh batch of our homemade fluffy slime this week! If you haven’t made fluffy slime then you are in for a real treat.  If you have already made fluffy slime then you know how awesome homemade slime is! Today we bring you a brand new theme slime, a St Patrick’s Day fluffy slime recipe with glitter, leprechauns, gold coins, and more!

Fluffy slime is an amazing texture that you have to try at least once. It starts out a bit messier than our other basic slime recipes, but the end result is fabulous!

Mounds of fluffy shaving cream make for a light airy texture. However, just like our leprechauns on St Patrick’s Day, this slime won’t stay quite as fluffy for very long!


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!

I will always let you know which basic slime recipe we used in our photographs, but I will also tell you which of the other basic recipes will work too!  Usually you can interchange several of the recipes depending on what you have on hand for slime supplies.

Here we use our Fluffy Slime recipe.  This homemade slime recipes is one of our favorite sensory play recipes!  We make it ALL the time because it is so quick and easy to whip up.   Add color, glitter, sequins, and then you are done!

NOTE: You can absolutely make this St Patrick’s Day slime with any of our regular slime recipes if you don’t want to make fluffy slime. The look will be just as fun and you can substitute white glue for clear glue for more vivid colors.

Regular saline solution slime, liquid starch slime, or borax slime recipes will all work wonderfully too!

The Science of Slime

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 forms 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 keeping the glue in a liquid state. 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 the 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…

St Patrick’s Day Fluffy Slime Recipe


  • 1/2 cup of White PVA glue
  • 3 cups of Shaving Cream Foam
  • 1/4 – 1/2 tsp Baking soda
  • Green Food Coloring
  • 1 tbsp Saline solution
  • Glitter, Confetti, Coins, Theme Accessories
  • Large Bowl, Spoon, Measuring Cups and Spoons


STEP 1:   Start by adding your shaving cream, glue and food coloring to a bowl.

Remember, you want to make the more green food coloring you add, the deeper the green will be! You can also add in green glitter for a fun two toned look!

STEP 2: Stir in the baking soda.

STEP 3: Mix in your saline solution and stir until slime forms and pulls away from the sides of bowl.

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. 

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

However, keep in mind that although adding more activator (saline solution) reduces the stickiness, but it will eventually create a stiffer slime.  You can always add but you can’t take away!

Slime Tip: Kneading Slime Is The Key!

We always recommend kneading your slime well after mixing. Kneading the slime really helps to improve it’s consistency. The trick with shaving cream/saline solution slime is to squirt a few drops of solution 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 ultra stretchy but can be stickier. However, keep in mind that although adding more solution reduces the stickiness right away, it will create a stiffer slime in the long run.

Our slime recipes are so easy to change up with different themes for holidays, seasons, favorite characters, or special occasions. Saline solution fluffy slime is always super stretchy and makes for great sensory play and science with the kids!

NOTE: Fluffy slime with shaving cream will loose some of it’s fluff due to the foam shaving losing air over time. However, it’s still tons of fun afterwards.
