A Bit Of Slime Science
We always like to include a bit of homemade slime science around here! 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 slime science all about? 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…
You add the borate ions to the mixture, and it then 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 rubbery 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! Experiment with making the slime more or less viscous with varying amounts of foam beads. Can you change the density?
Did you know that slime aligns with the Next Generation Science Standards (NGSS)?
It does and you can use slime making to explore states of matter and its interactions. Find out more below…

Christmas Tree Slime Recipe
Supplies:
- 1/2 cup of PVA Washable School Clear Glue
- 1/2 cup of water
- Food Coloring (we used green) and Glitter
- 1/4-1/2 Cup of Liquid Starch
Instructions:
STEP 1: In a bowl add 1/2 cup water and 1/2 cup of glue, and mix well to combine completely.
STEP 2: Now’s the time to add green color!
Mix the food coloring into the glue and water mixture.
STEP 3: Pour in 1/4 cup of liquid starch. You will see the slime immediately start to form. Keep stirring until you have a gooey blob of slime. The liquid should be gone!
STEP 4: Now time to start kneading your slime! It will appear stringy at first but just work it around with your hands and you will notice the consistency changes. You can also put it in a clean container and set it aside for 3 minutes, and you will also notice the change in consistency!
SLIME MAKING TIP: We always recommend kneading your slime well after mixing. Kneading the slime really helps to improve it’s consistency. The trick with liquid starch slime is to put a few drops of the liquid starch onto your hands before picking up the slime.
You can knead the slime in the bowl before you pick it up as well. This slime is stretchy but can be stickier. However, keep in mind that although adding more liquid starch reduces the stickiness, and it will eventually create a stiffer slime.
Now Time To Decorate Your Christmas Tree
Get ready for the best part, decorating your Christmas tree homemade slime! Gather your supplies and get started…
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!)
NEW! Add a styrofoam cone shape to your play as we did in our videos! It makes the tree decorating even more fun as your slime oozes over the cone in a tree shape.

Just gorgeous. Have scheduled to share on my Facebook page.
Thank you!
I could see my munchkins “decorating” this tree for a good long While! Great idea!
Looks so slimy but I think it is so cool and also it is unique, so creative. Ill try to make one of this in this coming christmas. Try to check this alternative christmas trees here guys http://www.exploretalent.com/articles/extremely-cool-alternative-christmas-tree-ideas/ . What do you think about it?
Hi! Thanks for all these great sensory ideas!! How long does the slime keep? I want to make it for my class a couple of days ahead of time-will it keep? Thanks.
Slime keeps nicely for about a week in my opinion. Loosely covered. Flip it around every now and then and you should be fine.
Thank you!
Wondering if I do this as a class project, would we make one recipe per student, or is one batch enough for several students? Thanks.
You can use one batch for 3-4 kids. The best thing is to grab some of those condiment cups from the dollar store. Makes just enough slime per person to still be fun!
