We decided as a family to forego any trick or treating experience, but still keep the fun in Halloween by hosting a family Halloween party! We love to dress up every year in different trendy family Halloween costumes and we still plan to show off our AMAZING (
still confidentia l!) family costume by modeling it in our front yard!
Halloween 2020 at our house will include an after dark glow-in-the-dark candy hunt, brain cupcakes, slime time, mystery sensory bags, spooky Halloween movies for kids, and lots of fun!
We also plan to drive around and play Halloween BINGO to see all the other decorations in town during the week of Halloween and we are competing in our town’s Halloween house decoration contest and have been busy making a ton of different DIY Halloween decor!
HOW TO MAKE SLIME WITHOUT GLUE
If you’ve scrolled through Pinterest any time lately, you’ll have noticed that there are tons of ways and methods to make slime. Recently I was asked how to make slime without glue.
I decided to put a twist on this recipe and see what happens when I use cold water instead of hot water to dissolve the guar gum.
We decided to not only make slime without glue, but to pair it with a Halloween theme for some seasonal sensory fun! Check out this awesome no glue slime recipe we came up with and turn into a zombie!
FUN DIY NO GLUE SLIME RECIPE!
The texture of this guar gum slime (ish) recipe is pretty unique and not sticky at all! It actually feels a lot like a gel ice pack to me. It’s a great sensory slime rather than a gooey slime and you can use it for Halloween surprise buckets or sensory bins!
You can even use this gooey slime to pretend to be a zombie!
This slime is not edible and adult supervision is required for making the recipe.
No Glue Slime Supplies
- 1/2 cup (120 mL) cold water
- two small cups
- 1 teaspoon (5 mL) guar gum
- Wooden popsicle sticks
- red food coloring
- 1/2 teaspoon (2.5 mL) borax (adult use only!)
- 2 teaspoons (10 mL) hot tap water
- Sealable plastic baggie or plastic slime storage container
You can find guar gum in the baking section of many grocery stores or on Amazon!
How to Make Brain Slime
To make brain slime, you begin by pouring cold water in one of the plastic cups. Using cold water instead of hot water makes the guar gum dissolve less and creates the clumpy factor in this recipe.
Use a wooden stick to stir the mixture until the mixture is thick and cloudy.
Next, add in a few drops of red food coloring and stir until blended. Allow the plastic cup to sit for 5-10 minutes while you work on the second mixture.
An adult should mix the borax and hot water in another plastic cup and stir until the borax is dissolved.
Finally, slowly pour the second mixture (borax cup) into the first mixture (guar gum liquid). Use a wooden stick to mix the liquids together. You’ll find that they make a clumpy gooey gunk that resembles a brain!
Congrats, you’ve made brain slime!
Note: This brain slime only lasts for a few days in a sealed plastic bag! When you are done with the slime, throw the bag in the garbage.
The Science of No Glue Slime!
This gooey slime uses guar gum, which is used as a thickener in foods. Guar gum comes from the guar plant that is grown in India and Pakistan. You can find guar gum in lots of favorite foods like ice cream and pudding!! Yum!
Guar gum is a natural polymer that binds with liquids to thicken them.

We Put the Boo in KaBOOm with this STEAM Activity
We set out to use items around the house to observe how a chemical reaction produces a new substance. Just kidding, we set out to make something EXPLODE.
To do that, we sat down and learned all about acids, bases, and chemical reactions and applied what we knew to our daily lives. I bored the kids with chemical equations and talked their ears off until surely they thought we weren’t doing anything exciting. Then, things went kaBOOm and they were thrilled!

It’s October and that means a ton of candy is coming to a household near you in the very near future! We don’t let the kids eat all of their candy. We pick at it and they eat a few pieces here and there, but let’s be real, there are some candies that no one really likes to eat.
We like to use those candies for experiments! In this yummy experiment, we are testing to see if sour candy is acidic with a simple acid-base reaction.
