Have you ever built a snowman on a late spring morning only to find that afternoon or the next day it looks a bit droopy or melty! We sure have, and it inspired us to make a melting snowman out of slime! Why slime? Because our homemade slime oozes and spreads of course, and makes the perfect look for our homemade melting snowman slime recipe. No real snow? No problem, make snow slime instead!

All of our holiday, seasonal, and everyday theme slimes use one of our 4 basic slime recipes that are super easy to make including our homemade melting snowman slime recipe! We make slime all the time, and these have become our four go-to favorite slime making recipes.

I will always let you know which 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 for slime supplies.

Make sure to read through our recommended slime supplies and print out a slime supplies checklist for your next trip to the store. You will see everything we love using to make slime. We also have a slime kit that you might want to get set up for winter vacation!

Make sure to read all the way to the bottom to check out all our slime making resources. Below the supplies list, you will see more black click here boxes for slime recipes that will work with this snowman theme slime.

Melting Snowman Slime Recipe for Kids Homemade Winter Slime


RECIPE: We chose the liquid starch slime recipe for our snowman!

First you need to choose a recipe from one of our 4 basic slime recipes. You can choose a liquid starch slime, saline slime, borax slime, and even fluffy slime to make this snowman slime theme. Check out the ingredients for each and see which one works best for you!





White PVA Washable School Glue

Liquid Starch


Bowl, Measuring Cups, Spoon


Styrofoam Ball {use whatever size you can find}



Craft Items {to decorate snowman slime}

Whip up your recipe and get started with the play! I noticed packages of small white foam balls at the dollar store the other day. The smaller the ball the more melt you will have going on unless you make a double recipe of slime!

If you don’t have the styrofoam ball, just use the decorations on a pile of white snow slime. You will have a very melty snowman slime quickly! Still lots of fun.


What’s the science behind the slime? The borate ions in the slime activator  {sodium borate, borax powder, or boric acid} mixes 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.

The addition of water is important to this process. Think about when you leave a gob of glue out, and you find it hard and rubbery the next day.

When you add the borate ions to the mixture, it 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 is thicker and rubberier like 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 actually last a few days uncovered. If the top gets crusty just 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.

Slime is easy to make, but it’s important that you read the directions, use the correct ingredients, measure accurately, and have a little patience if you don’t succeed the first time. Remember, it’s a recipe just like baking!


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 lack of attention to supplies needed, reading the recipe, and actually 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!
