MAKING YOUR VALENTINES DAY CRUNCHY SLIME RECIPE

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

This crunchy slime uses our saline solution slime recipe.

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. After the supplies listed below you will see click here black boxes for slime recipes that will work with this theme.

Here are the two best recipes to make this slime. Each recipe has full instructions and its own video! I highly suggest you become familiar with our 4 basic slime recipes. Then you can easily make so many fun themes!

THE SCIENCE BEHIND VALENTINES DAY CRUNCHY SLIME RECIPE

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.The water helps the strands or molecules slide more easily over themselves creating cool ooze!

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!

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 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!

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 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.
