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 holiday 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!

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!

Is slime a liquid or solid? We call it a Non-newtonian fluid because it’s a little bit of both!

The best slime recipe starts with the right slime ingredients. Make sure to follow along with our measurements. Start by adding your clear glue and water to a bowl and grab a mixing utensil. Mix it up and add food coloring and glitter as desired!

BEST SLIME ACTIVATORS

Add in your slime activator (liquid starch) to complete the chemical reaction you read about above in the science behind the slime section. If you scrolled past it, go back and read it with your kids!

You can also learn more about all our favorite slime activators here. Keep in mind that liquid starch, saline solution, and borax powder are all in the boron family. Neither of these ingredients are truly borax free.

KNEADING YOUR SLIME IS KEY!

We always recommend kneading your slime well after mixing. Kneading the slime really helps to improve it’s consistency.

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, it will create a stiffer slime.

LIQUID STARCH SLIME RECIPE FOR MAKING HALLOWEEN SLIME

STEP 1: Add 1/2 cup of Elmers Glue to your bowl (add more glitter if desired).

STEP 2: Mix with a 1/2 cup of water.

STEP 3: Add food coloring and glitter!

STEP 4: Stir in 1/4-1/2 liquid starch!

If your  slime still feels too sticky, you may need a few more drops of liquid starch.

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

DECORATE YOUR CHRISTMAS TREE SLIME

Get ready for the best part, decorating your Christmas tree homemade slime! Gather your supplies and get started. We have two ways you can play.

We had so much fun decorating our homemade Christmas tree slime and those little hands worked hard pushing the ornaments into the slime and even picking them up. (Sneaky fine motor skills too!)

Add a cookie cutter too. You can cut out a tree shape and watch it ooze back out to a blob. That’s great slime science!

NEW! Add a styrofoam cone shape to your play like we did in our videos! It makes the tree decorating even more fun as your slime oozes over the cone in a tree shape.

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.
