The Best Sparkly Witches’ Brew Halloween Slime Recipe

Ingredients

To make this Sparkly Witches’ Brew Halloween Slime recipe, we used our classic Clear Slime Recipe. You’ll need the following:

1/2 cup Elmer’s Clear Glue
1/2 cup Warm Water
1/2 teaspoon Baking Soda
1-2 tablespoons Contact Lens Solution (make sure it contains boric acid or sodium borate): We used Bauch+Lomb Renu.
Optional: Food coloring, Glitter, Halloween confetti or sequins to add extra spooky sparkle!

Instructions

1. Mix Your Baking Soda and Water

In a separate small bowl, dissolve 1/2 tsp baking soda into 1/2 cup warm water. Be sure the baking soda dissolves completely and then let the mixture cool slightly. This ensures you won’t get a sticky or runny slime later on.

2. Add Glue

Add 1/2 cup clear glue to a mixing bowl.

3. Combine Glue and Water Mixture

Slowly add the water and baking soda mixture to the clear glue in the mixing bowl. It’s important to stir gently so that you don’t create too many bubbles. Fewer bubbles in this step means clearer slime in the end! If you’re really trying to get that perfect crystal-clear look, slow and steady wins the race.

4. Add sparkles!

Now’s the time to make your Sparkly Witches’ Brew Halloween Slime truly magical (and a little creepy!). We mixed in Halloween confetti (pumpkins, spiders, jack o’ lanterns, stars, and more) and a mix of fine and chuncky purple glitter for a sparkly touch. I added a couple drops of purple food coloring to give it a witchy potion vibe.

Pro Tip: The more you mix in, the cloudier your slime might get. If keeping it clear is your goal, stick to glitter or very small items.

5. Add Contact Solution

Slowly stir in your contact lens solution (start with about 1 tablespoon). Keep stirring for a few minutes until you notice the mixture starts to firm up and pull away from the sides of the bowl.

If it’s still too sticky and not pulling away from the edges of the bowl after mixing, just add a little more contact lens solution, a little bit at a time. Be careful not to overdo it though, or you might end up with rubbery slime instead of that smooth, stretchy texture you’re aiming for.

6. Knead the Slime

Time to get hands-on! Add a couple of drops of contact solution to your hands and knead the slime in your hands for a few minutes. Kneading helps the slime become less sticky and gives it that perfect stretchiness.

If it’s still a little too sticky, just keep adding tiny amounts of contact solution until it reaches the right consistency.

Tips and Tricks For The Best Sparkly Witches’ Brew Halloween Slime

Too Sticky?

If your slime is sticking to everything, add just a few drops of contact lens solution and keep kneading. Be cautious not to add too much at once. Clear glue slime is naturally firmer than white glue slime, so it’s all about finding that perfect balance.

Cloudy Slime?

It’s completely normal for your slime to look cloudy right after mixing. If you mixed it too quickly or squished it too much while playing, that introduces more bubbles into the slime. No worries! Just let the slime sit in an airtight container for a few days and the bubbles will work their way out. For an extra-clear result, stir gently during each step.

Choose the Right Contact Lens Solution

Check the label of your contact lens solution to ensure it contains boric acid or sodium borate. This is the key ingredient that activates the slime. We used Bauch+Lomb Renu and it worked really well, but the amount of boric acid can vary between brands. If your slime isn’t coming together as expected, try adjusting the amount of contact solution.

How to Store Your Sparkly Witches’ Brew Halloween Slime

Once you’ve perfected your Sparkly Witches’ Brew Halloween Slime recipe, it’s important to store it properly so it lasts as long as possible. Keep your slime in an airtight container when you’re not playing with it. This will prevent it from drying out. This Halloween slime recipe can last for several weeks depending on how much you play with it.

If the slime starts to feel too firm after a while, you can knead in a tiny bit of water to soften it up again.
