THE SCIENCE BEHIND OUR VALENTINE CRUNCHY SLIME
We always like to include a bit of homemade slime science around here, and that’s perfect for exploring chemistry with a candy corn 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! Read more about slime science here!
VALENTINE CRUNCHY SLIME RECIPE
- 1/2 Cup Clear Washable PVA School Glue
- 1/2 Cup Water
- 1/2 Teaspoon Baking Soda
- 1 tablespoon Saline Solution (must contain sodium borate and boric acid)
- Food Coloring
- 1 to 2 Cups Fishbowl Crunchy Beads (red or clear or whatever color you want to make)
- Plastic Hearts (optional, found these at the dollar store or craft store)
HOW TO MAKE VALENTINE’S CRUNCHY SLIME
STEP 1: In a bowl mix 1/2 cup water and 1/2 cup of glue well to combine completely.
STEP 2: Add red food coloring and mix.
STEP 3: Add a good amount of crunchy beads and stir well.
STEP 4: Stir in the baking soda.
Baking soda helps to firm and form the slime. You can play around with how much you add but we prefer between 1/4 and 1/2 tsp per batch.
STEP 5: Mix in saline solution and stir until slime forms and pulls away from sides of the bowl.
If your slime still feels too sticky, you may need a few more drops of saline solution. As I mentioned above, start by squirting a few drops of the solution onto your hands and kneading your slime longer. You can always add but you can’t take away. Saline solution is preferred over contact solution.
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!
