The Science Of Slime

We always like to include a bit of homemade slime science around here. What’s the science behind the slime? 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 flow past one another keeping the glue in a liquid state. Until…

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 thicker and rubberier 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!

Fluffy Slime Recipe

SLIME TIP: Always follow the directions carefully! Slime making is a recipe just like baking cookies. An alternative for this slime is to experiment with the amount of shaving cream you want to use.

Ingredients:

It is so important to start off with the right ingredients!

• 1/2 cup White Washable PVA School Glue
• 3 cups Foam Shaving Cream
• 1 tbsp Saline Solution
• 1/4-1/2 tsp Baking Soda

How To Make Fluffy Slime:

STEP 1: Measure and add 3-4 generous cups of foam shaving cream to a large mixing bowl. Go ahead and experiment with an amount that makes you happy!

STEP 2: Next, add food coloring if desired and gently stir to mix color.

STEP 3: Measure and add 1/2 cup of white glue to your bowl. Then gently stir to combine.

Pin

STEP 4: Add 1/2 teaspoon of baking soda to the mixture and gently stir.

Pin

STEP 5: Lastly, measure out 1 tablespoon of saline solution or contact solution (must contain borate ions) and add to bowl.

Pin

STEP 6:Whip the mixture to activate the slime. It will begin to pull away from sides and bottom of bowl.

STEP 7:Pick up your slime and knead it until smooth and stretchy and no longer sticky.

SLIME TIP: Squeeze a few drops of saline solution on your hands before picking up your slime makes it stick less while you knead it. Kneading it is important to improving the consistency of the slime.

Don’t go crazy adding more saline solution until you have spent some time kneading it. This will reduce the stickiness. If you add too much saline initially, you will end up with rubbery slime.

How To Store 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.

FLUFFY SLIME: Fluffy slime doesn’t stay fluffy for over a day. As you know, the foam shaving cream is filled with air and decreases over time. I wouldn’t suggest fluffy slime as the best party favor.

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.
