Are you waiting for spring and summer like I am. It's not here yet, but I can totally share a flowery spring slime recipe with you just the same. Learning how to make clear slime is the perfect way to showcase vibrant sparkly confetti for any season or holiday!


I love theme confetti and it’s such an easy and quick way to dress up a batch of homemade slime for any season or holiday. Looking back, I am pretty sure we have used some sort of theme confetti for every single holiday or season in the past few years. Yes, we have been making slime that long!

Flower confetti is a fun and colorful add in for a spring theme slime recipe. We have grown flowers, made crystal flowers, even yarn flowers and now have a flowery slime recipe to enjoy too!

Because we have been making slime for years, I feel extremely confident in our homemade slime recipes and want to pass them along to you. Slime making is a bit of a science, a cooking lesson, and an art form all in one! You can read more about the science below.

Spring Slime Recipe with Flower Confetti and Homemade Clear Glue 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 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…

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!

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!

Borax powder is the best slime activator for creating a truly clear slime. However, if using borax powder is not an option for you, check out our saline solution slime recipe here.

Make sure to wash hands thoroughly after playing with slime.  If your slime gets a little messy, it does happen, check out my tips for how to get slime out of clothes and hair!


  • 1/2 cup Washable PVA Clear Glue
  • 1/2 cup water to mix with glue and 1/2 cup of warm water to mix with the borax powder
  • 1/4 tsp Borax Powder {laundry aisle}
  • Measuring cups, bowl, spoon or craft sticks
  • Flower confetti and glitter as desired


STEP 1:  In a bowl mix 1/2 cup water and 1/2 cup of glue.  Mix well to combine completely.

STEP 2: Add your flower confetti and stir well.

STEP 3: Make up your slime activator by mixing together 1/4 tsp borax powder and 1/2 cup warm water in a separate bowl.   Hot tap water is fine and does not need to be boiled.

This step is best done by an adult!  

Spend a minute stirring to make sure the borax powder is well mixed in.

STEP 4: Add the borax solution {borax powder and water} to the glue/water mixture. Start stirring! 

Your slime will begin to form instantly. Keep stirring until your slime has formed and remove immediately to a dry container.

With our new ratio of borax powder to water, you should not have any leftover liquid in the bowl. If you do keep stirring. With higher ratios of borax to water, you may have leftover liquid.

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 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 (borax powder) reduces the stickiness, it will eventually create a stiffer slime.  You can always add but you can’t take away!

Freshly mixed spring slime recipe is ready for little hands! Slime is not only awesome science, but it is also an amazing sensory play!

Clear Spring Slime Recipe with Flower Confetti


We made this large batch of clear slime and noticed it was filled with air bubbles so it wasn’t crystal clear. It didn’t look like glass at all!

We stuck it in a glass container and put a lid on it and it ended up sitting on the counter untouched for a day and a half while we were busy with swim and school and friends.

My son checked on it and noticed that the large air bubbles were much smaller.

We let it sit even longer and the bubbles were even smaller and almost nonexistent. Well, there’s only so long you can let the slime sit before playing with it again.

We did test this out on three separate batches of our clear glue slime to make sure!
