EASY HALLOWEEN FLOAM IDEAS

We made this Halloween Floam with white glue, food coloring, and foam beads. However, clear glue is super easy to use and also works well for this recipe, but your color will be slightly different! You can also use color foam beads.

Come up with your own favorite Halloween theme characters:

  • black slime and foam beads for a black cat
  • green slime and foam beads for monster, goblin, or Frankenstein
  • orange slime and foam beads for a jack o lantern
  • white slime and foam beads for a ghost
  • purple slime and foam beads for a witch or wizard

HALLOWEEN FLOAM SLIME TIPS 

The base for this Halloween floam uses one of our most basic slime recipes which is white glue, water, baking soda, and saline solution. NOTE: for a stiffer Floam you can omit the water you would normally add to the basic saline solution slime recipe. Now if you don’t want to use a saline solution, you can absolutely test out one of our other basic recipes using liquid starch or borax powder.

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!

HALLOWEEN FLOAM INGREDIENTS

As I mentioned above, you can use any of our basic slime recipes for our Halloween slime ideas, but we like our basic saline solution slime recipe with the Elmers clear washable school glue.

HALLOWEEN FLOAM RECIPE DIRECTIONS BELOW 

This fun Halloween slime activity calls for three batches of our easy Halloween Floam. You can make more or less depending on your character ideas! In general, several kids can share one batch of this floam, but it may be harder to make the faces.

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 and glitter as desired!

Combine water, glue, and food coloring in a large bowl and mix well! Next add baking soda.

You can add your foam beads before you add your slime activator (saline solution) or after the slime is made. We prefer adding it during the mixing process, but it works either way! If you didn’t add enough beads the first time you can always squish more in after the slime is mixed.

BEST SLIME ACTIVATORS

Add in your slime activator (baking soda and saline solution)  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!

What does the baking soda do? It adds the firmness the mixture needs so you can pick it up. This ingredient is a great variable to tinker with for a science experiment!

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.

We always recommend kneading your slime well after mixing. Kneading the slime really helps to improve its 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.

Our slime recipes are so easy to change up with different themes for holidays, seasons, favorite characters, or special occasions. Saline solution is always super stretchy and makes for great sensory play and science with the kids!

Adding foam beads creates a whole other sensory experience the kids will love, especially the popping noises.

SALINE SOLUTION SLIME RECIPE FOR MAKING HALLOWEEN SLIME IDEAS

STEP 1: Add 1/2 cup of Elmers Glue to your bowl

STEP 2: Mix with a 1/2 cup of water (you can try omitting this for a thicker floam).

STEP 3: Add food coloring as desired STEP 4: Stir in 1/2 tsp baking soda STEP 5: Stir in a cup and quarter of foam slime beads or as many as you desire! STEP 6: Mix in 1 tbsp saline solution and stir until slime forms and pulls away from sides of 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.

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.

Use our “How To Fix Your Slime” guide if you are having trouble and make sure to watch my live start to finish slime video here.

TO PLAY: Cut fun faces out of black foam paper and decorate your Halloween floam characters! Alternatively, you can add plastic spiders and any assortment for creepy crawlies and google eyes.

SLIME SCIENCE AND CHEMISTRY

We always like to include a bit of homemade slime science around here, and that’s perfect for exploring Chemistry with a fun Halloween 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 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! 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?

STORING YOUR SLIME

This floam makes a fun non-candy Halloween treat for the kiddos to make at parties or give to friends! Small plastic containers work well. You can even take a sharpie and draw a face on the outside of the container or cut and paste more foam shapes!

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.
