New Years Eve Slime Recipe and Science Activity for Kids

Celebrate with slime? Around here that’s absolutely what we do! We make a slime for everything. Other people say it with a card, well we say to with homemade slime. I love planning fun ideas for New Years eve and it usually involves a lot of confetti. We love homemade slime, so of course we need a batch of our gorgeous New Years Eve slime recipe to ring in the New Year!


We make New Years eve a big deal around here though I don’t think I have stayed away the whole night to midnight. I can guarantee my son can. He will end up tucking me into bed and watching the ball drop with my husband.

This year we have started making some awesome videos of our slime being made! This is a great way to see how easy the slime recipe is to make. Check out the video below for this New Years slime!

Slime making is even more fun when you add in creative themes like a celebration or party theme.  Our Homemade Celebration new Years Eve Slime Recipe is yet another AMAZING slime recipe we can show you how to make.




We made this New Years Eve slime with clear glue, glitter and confetti bursts.

Here are a few more fun and easy New Years Eve slime ideas to try too!

*NOTE: This slime can also be made using our saline solution slime recipe too! Click here.


Classic borax slime is one of our most basic slime recipes which is clear glue, water, and borax powder.

Now if you don’t want to use saline solution, you can absolutely test out one of our other basic recipes using liquid starch or saline solution.

Our easy, “how to make” slime recipes will show you how to master slime in 5 minutes! We have spent years tinkering with our 4 now 5 favorite basic slime recipes to make sure you can make the BEST slime every time!

We believe learning how to make slime shouldn’t be disappointing or frustrating! That’s why we want to take the guess work out of making slime!

  • Discover the best slime ingredients and get the right slime supplies the first time!
  • Make easy fluffy slime recipes that really work!

1/4 tsp Borax Powder {found in laundry detergent aisle}.

1/2 cup Elmer’s Clear  Washable PVA School Glue

1 cup of Water divided into 1/2 cups

Glitter, Snowflake Confetti, Food Coloring (optional)

Step by Step Recipe Listed Below Pictures


This fun celebration slime activity calls for one batch of our easy borax slime recipe. You can make more or less depending on your ideas! *You can also use our saline solution recipe! Click here

The best slime recipe starts with the right slime ingredients. Make sure to follow along with our measurements. Start by adding your glue and water to a bowl and grab a mixing utensil. Mix it up and add food coloring, glitter, and confetti as desired!

New Years Slime Recipe with Clear Glue

Add the sparkle and shine with glitter and confetti!


Add in your slime activator (borax powder) to complete the chemical reaction you read about above in the science behind the slime section. If you scrolled past it, go back and read it with your kids!

You can also learn more about all our favorite slime activators here. Keep in mind that liquid starch, saline solution, and borax powder are all in the boron family. Neither of these ingredients are truly borax free.

Mix 1/4 tsp of borax powder into a 1/2 of warm water to make your slime activator solution.

Borax powder mixed with hot water is the slime activator that creates the rubbery, slimy texture you can’t wait to play with! It’s super easy to whip up this homemade slime recipe once you get the hang of it.

New Years Eve Slime Recipe with Borax Slime Recipe


Party Confetti New Yeasr Eve Slime for Kids



We always recommend kneading your slime well after mixing. Kneading the slime really helps to improve it’s consistency. The trick with saline solution slime is to squirt a few drops of solution 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 saline solution reduces the stickiness, and it will eventually create a stiffer slime.


1: Dissolve 1/4 teaspoon of borax powder into 1/2 cup of warm water in one of the three bowls. Mix this thoroughly.

BORAX SLIME NOTE: We have recently tinkered with our recipe and found that for a better oozing slime 1/4 tsp of powder is best (if using clear glue always use 1/4 tsp). If you like a firmer slime and are using white glue, we experimented with 1/2 tsp and 1 tsp. 1 tsp makes a much firmer putty like slime.

2: In the second bowl measure out about 1/2 cup of clear glue and mix with 1/2 cup of water until well mixed

3: Pour borax/water mixture into glue/water mixture and stir it up!

4: You will see it come together right away. It will seem stringy and clumpy, but that’s ok! Remove from bowl.

5: Spend a few minutes kneading the mixture together. You may have left over borax solution.

6: Store in clean container with cover.  I love the deli style plastic food storage containers.

TOO STICKY? If your slime still feels too sticky, you may need a few more drops of borax solution.  You can always add but you can’t take away. The more activator solution you add, the stiffer the slime will become over time. Make sure to spend extra time kneading the slime instead!

SLIME NOTE: We have found that the Elmers specialty glues tend to be a bit stickier than their regular glue, and we prefer our 2 ingredient slime recipe for this glue. The blue glitter glue would be fun for this snowflake slime too!

New Years Eve Slime Recipe with Celebration Confetti


Slime lasts quite awhile! 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 in my recommended slime supplies list here.

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 as seen here.

We always like to include a bit of homemade slime science around here, and that’s perfect for exploring Chemistry with a fun winter 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! Experiment with making the slime more or less viscous with varying amounts of foam beads. Can you change the density?
