DIY bubbling slime is one of those activities that every parent or preschool teacher should have in their back pocket. Nothing gets kids more excited than a craft that looks like pure magic!
The beauty of this bubbling slime recipe is that it’s more than just messy play. It’s a science experiment disguised as a craft, a way to encourage early STEM curiosity while giving kids the sensory play they crave.
Parents are always searching for different slime recipes but many recipes are too complicated or not safe for toddlers. That’s why this bubbling slime recipe stands out: simple supplies, a fast setup, and a safe, non-toxic reaction that kids can explore without worry.
What makes it even more exciting is the element of surprise! The mixture looks ordinary at first, but as soon as the vinegar and baking soda meet, the slime bubbles and fizzes like a volcano. It’s part craft, part experiment, and part magic show.
If you’ve been wanting an activity that keeps toddlers and preschoolers engaged while sneaking in some science learning, this bubbling slime is the answer.
By the time you’re done reading, you’ll not only know how to make this slime at home but also understand the science behind it, learn ways to add creative twists, and see why it’s quickly becoming one of the top preschool sensory activities. Let’s dive into the bubbly fun!
Why Bubbling Slime Recipe Is the Perfect Sensory Activity
When parents and teachers think about sensory activities, they often imagine finger painting or playdough. But the bubbling slime recipe takes sensory play to the next level. Here’s why:
Engages multiple senses at once – Your kid will enjoy feeling the squish, seeing the bubbles, and hearing the fizz.
Combines art, science, and play – Your child will love choosing the colors of their slime, watching it bubble and fizz, and playing with it for weeks after making it.
Safe for toddlers and preschoolers – When you use non-toxic school glue and household ingredients, this slime, unlike many others, won’t be harmful to your toddler.
Motor skill practice – As your child stretches and kneads the slime, it’ll help develop their finger strength.
Encourages curiosity – The experiment and activity will have your child naturally asking, “Why is it bubbling?” which will give you an opportunity to introduce them to the science of it all.

How to Make This Bubbling Slime Recipe
Before we jump into the fun, let’s talk about the slime supplies. Here’s what you’ll need:
- ½ cup clear school glue
- 5 tablespoons baking soda
- Red food coloring (or any color you choose)
- Red glitter (or glitter in any color for sparkle)
- ¼ cup white vinegar
- 2 teaspoons contact solution (must contain boric acid)
If you’ve ever made DIY slime for kids before, you’ll notice this recipe uses baking soda and vinegar for the fizzing reaction, which makes it extra exciting.
Making slime may look complicated, but with this recipe, it’s as easy as measuring, mixing, and watching the magic unfold.
Instructions
Place everything on the table before starting. Having kids help line up the bowls, spoons, and ingredients makes them feel part of the process.
Add ½ cup of clear school glue and 2 tablespoons of baking soda to a bowl. Stir until smooth. Add 3–4 drops of food coloring and a sprinkle of glitter. Kids love choosing colors—it’s a great way to personalize the slime.
In a separate cup, mix ¼ cup vinegar with 2 teaspoons contact solution. This is the bubbling agent that brings the slime to life.
Pour the vinegar mixture into the glue bowl. Stir gently. Within seconds, you’ll see bubbles fizzing up and spreading across the slime. Toddlers will squeal with delight as the mixture grows and expands.
When the bubbling slows, add the remaining 3 tablespoons baking soda.
Stir again until the mixture thickens into stretchy slime. Kids can switch from spoons to hands at this stage for more sensory fun.
Place your slime in a container with an airtight lid or Ziplock bag. This keeps it soft and reusable for future play sessions.
Tips for Stress-Free Slime Making
- Prep your workspace with table covers or trays.
- Use child-safe supplies like non-toxic glue.
- Let kids help with safe steps like stirring or adding glitter.
- Store slime properly in airtight containers to reuse later.
- Pair with other crafts like homemade squishies or paper squishy ideas for variety.
These simple steps turn potential chaos into organized fun.
The Science Behind This Bubbling Slime
Kids love slime for the fun, but adults know the hidden value: it’s science in action. The bubbling effect happens because of the classic vinegar and baking soda reaction.
Vinegar is an acid and baking soda is a base. When combined, they release carbon dioxide gas. The gas creates bubbles, making the slime fizz and expand.
This reaction is the same one used in volcano science projects for kids. By adding it into slime, you’re giving toddlers a hands-on introduction to chemistry without making it feel like a lesson.
For preschool teachers, this activity doubles as a science experiment that connects directly to early learning standards.
It’s no wonder many parents and educators include slime in biology projects, cool science experiments, and preschool science crafts. The bubbling slime recipe becomes a bridge between playtime and education!
Sensory Benefits of Bubbling Slime Recipe for Kids
Sensory activities like slime are more than just fun. They support cognitive development, teach problem-solving, and help kids regulate emotions. Here’s some of those additional benefits:
Emotional regulation – Squishing slime can calm your child and reduce stress by encouraging them to pause and let their minds wander.
Sensory exploration – The textures, fizzing sounds, and colors create a full sensory experience that your child will want to come back to again and again.
Curiosity and problem-solving – This activity will encourage your kid to ask questions and explore cause and effect.
Social play – This slime is something you will want to share during playdates or classrooms.
