SPRING SLIME ACTIVITIES AND CHALLENGES
Spring Slime Themes
Kids love to play with slimes, making them unique to seasons, holidays, or special themes! Slime-making is even more fun when you add in slime-making challenges like the FREE printable below. We have many spring activities to share and are always adding more!
Learning how to make homemade slime is much simpler than you might think. Slime-making is even more fun when you add 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 several slime ideas to share and are always adding more. Our Spring Slime Making Challenge is yet another AMAZING slime recipe we can show you how to make.
Quick Slime Science For Kids
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 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 of long, repeating, and identical strands or molecules. These molecules flow past one another, keeping the glue liquid. 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 a clump of spaghetti!
Is slime liquid or solid?
We call it a Non-Newtonian fluid because it’s a bit of both! Experiment with making the slime more or less viscous with varying amounts of foam beads. Can you change the density? If you enjoy slime, try our rainbow oobleck too! It’s also a Non-newtonian fluid.

Saline Solution Slime Recipe
Which saline solution is best for slime? We pick up our saline solution in the grocery store! You can also find it on Amazon, Walmart, Target, and your pharmacy. Ensure the saline solution contains borate ions, making it a slime activator.
YOU WILL NEED THE FOLLOWING:
- 1/2 cup Clear or White PVA School Glue
- 1 tablespoon Saline Solution (must contain boric acid and sodium borate). Good brands include Target Up and Up as well as Equate brand!
- 1/2 cup of Water
- 1/4-1/2 tsp Baking Soda
- Food coloring, confetti, glitter, and other fun mix-ins
HOW TO MAKE SALINE SOLUTION 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 the 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 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 it away. Saline solution is preferred over contact solution.
STEP 5: Start kneading your slime!
It will appear stringy at first but 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 solution onto your hands before picking up the slime.
You can also knead the slime in the bowl before you pick it up. This slime is stretchy but can be stickier. However, remember that adding more activators (saline solution) reduces the stickiness, but it will create a stiffer slime that is more prone to breaking than stretching when pulled.
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?

More Slime Tips and Tricks
- Baking soda helps to firm and form the slime. You can experiment with your own ratios!
- BAKING SODA SLIME TIP: Clear glue slime usually doesn’t need as much baking soda as white glue slime!
- The saline solution is the slime activator and helps the slime to get its rubbery texture! Be careful; adding too much saline solution can make for a slime that’s too stiff and not stretchy!
- Give this slime a fast stir to activate the mixture. You will notice the thickness change as you stir it. You will also notice the volume of your mixture changes as you whip it up.
- Slime is awesome for tactile sensory play, but wash your hands and surfaces after making and playing with slime.
- Make a few batches in different colors and swirl them together, as shown in the cover photo or below! Think of what other color combinations your kids would enjoy. Slime-making is only limited by the imagination of the hands creating it!
Stretchy Slime vs. Sticky Slime
Which slime is the stretchiest? This slime recipe is by far my 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 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. Remember that any recipe will come out just a bit differently 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 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 suggest reusable containers from the dollar store, 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!
