SLIME SCIENCE AND CHEMISTRY

We always like to include a bit of homemade slime science around here, and that’s perfect for exploring Chemistry with a fun fall theme. 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 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 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…

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!

SLIME FOR NGSS: Did you know that slime aligns with the Next Generation Science Standards? It does and you can use slime making to explore states of matter and its interactions. Check out NGSS 2-PS1-1 for more information!

HALLOWEEN SLIME INGREDIENTS

As I mentioned above, you can use any of our basic slime recipes for this fall inspired cinnamon scented slime, but we like our basic saline solution slime recipe with the Elmers white washable school glue. I will link the products we used here with Amazon affiliate links below.

1: Dissolve 1/4 teaspoon of borax powder into 1/2 cup of warm water in one of the three bowls. Mix this thoroughly.

BORAX SLIME NOTE: We have recently tinkered with our recipe and found that for a better oozing slime 1/4 tsp of powder is best (if using clear glue always use 1/4 tsp). If you like a firmer slime and are using white glue, we experimented with 1/2 tsp and 1 tsp. 1 tsp makes a much firmer putty like slime.

2: In the second bowl measure out about 1/2 cup of clear glue and mix with 1/2 cup of water until well mixed

3: Pour borax/water mixture into glue/water mixture and stir it up!

4: You will see it come together right away. It will seem stringy and clumpy, but that’s ok! Remove from bowl.

5: Spend a few minutes kneading the mixture together. You may have left over borax solution.

6: Store in clean container with cover.  I love the deli style plastic food storage containers.

If your  slime still feels too sticky, you may need a few more drops of borax solution.  You can always add but you can’t take away. Adding to much activator will temporarily make the slime less sticky but will also make the slime more rubbery and brittle over time. Knead, knead, and knead some more!

NOTE: We have found that the Elmers Specialty Glues tend to be a bit stickier than their regular clear glue and we prefer our 2 ingredient slime recipe for this glue.

Halloween party favors can be so much more than candy. Even better it means that all kids regardless of allergies can enjoy the fun and excitement of Halloween. If you are throwing a Halloween party or even a Halloween play date, make slime with the kids. They will have a blast and so will you!

STORING YOUR SLIME

Slime lasts quite awhile! I get a lot of questions regarding how I store my slime. We use reusable containers in either plastic or glass. Make sure to keep your slime clean and it will last for several weeks. I love the deli style containers in my recommended slime supplies list here.

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 or grocery store or even Amazon. For large groups we have used condiment containers as seen in the pictures above!
