Learning how to make homemade slime is much simpler than you might think. Slime making is even more fun when you add in creative themes for the season as we have done for spring! This spring slime making challenge is an awesome way to get creative with slime! We have quite a few slime ideas to share, and we are always adding more. Our Spring Slime Making Challenge is yet another AMAZING slime recipe we can show you how to make.
Oh and slime is science too, so don’t miss the great information on the science behind this easy slime below. Watch our awesome slime videos and see how easy it is to make the best slime!
THE SCIENCE OF SPRING SLIME
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 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…
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…
BASIC SALINE SLIME RECIPE
You can use this basic slime recipe as a base for all your spring slime theme challenge!
I always encourage my readers to read through our recommended slime supplies list and How To Fix Slime Guide before making slime for the first time. Learning how to stock your pantry with the best slime ingredients is easy!
YOU WILL NEED:
- 1/2 cup Clear or White PVA School Glue
- 1 tablespoon Saline Solution (must contain boric acid and sodium borate)
- 1/2 cup of Water
- 1/4-1/2 tsp Baking Soda
- Food coloring, confetti, glitter, and other fun mix-ins
For this awesome flower pot theme spring slime challenge we used the following items:
- Brown food coloring for dirt (you can even add some real dirt instead!)
- Small plastic pot
- Fake flowers
HOW TO MAKE SALINE SLIME:
STEP 1: In a bowl mix 1/2 cup water and 1/2 cup of glue well to combine completely.
STEP 2: Now’s the time to add color, glitter, or confetti! Remember when you add color to white glue, the color will be lighter. Use clear glue for jewel-toned colors!
STEP 3: Stir in 1/4- 1/2 tsp 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. I get asked all the time why do you need baking soda for slime. Baking soda helps to improve the firmness of the slime. You can experiment with your own ratios!
STEP 4: Mix in 1 tbsp saline solution and stir until slime forms and pulls away from sides of the bowl. This is exactly how much you will need with the Target Sensitive Eyes brand, but other brands may differ slightly!
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.
STEP 5: 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 TIP: We always recommend kneading your slime well after mixing. Kneading the slime really helps to improve its consistency. The trick with this slime is to put a few drops of the saline soluti9n 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 activator (saline solution) reduces the stickiness, and it will eventually create a stiffer slime.
Go ahead and plant a pot of slimy flowers!
You will love how easy and stretchy this saline slime is to make, and play with too! Once you have your desired slime consistency, time to have fun! How big of a stretch can you get without the slime breaking?
STRETCHY SLIME vs. STICKY SLIME
Which slime is the stretchiest? This slime recipe is by far my most favorite slime recipe for stretchy slime!
A stickier slime will be a stretchier slime no doubt. A less sticky slime will be a firmer slime. However, not everyone loves a sticky slime! As you continue to knead the slime, the stickiness will lessen.
Tinkering with the baking soda and saline amounts will change the consistency of the slime to thinner or thicker. Keep in mind that any recipe will come out just a bit different on any given day. This is really a great chemistry experiment, and one of the things you will learn is that slime is meant to be stretched slowly.
HOW DO YOU STORE SLIME?
Slime lasts quite a while! 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 I have listed in my recommended slime supplies list.
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 and labels as seen here.
We have the best resources to look through before, during, and after making your (KEYWORD) slime! Make sure to go back and read the slime science above too!
