Looking for a quick, easy, and absolutely fascinating science experiment for kids? The Sticky Ice Experiment is perfect!
It’s simple, requires just a few kitchen supplies, and teaches kids the magic of salt and ice. Plus, it’s an exciting way to introduce basic scientific concepts in a hands-on way. Let’s get started!
Why Do Science Experiments with Kids?
Young kids are natural scientists—they love asking “why,” testing ideas, and exploring the world. Science experiments like this one encourage:
Critical Thinking & Problem-Solving – Why does the ice stick to the string? How does salt change ice?
Language Development – Kids will describe what they see and make predictions.
Fine Motor Skills – Sprinkling salt, handling ice cubes, and lifting string all help develop coordination.
Cause & Effect Learning – Kids will see how their actions lead to specific outcomes.
A Love for Science! – Fun experiments keep kids excited about learning.
The Science Behind the Sticky Ice Experiment
So, what’s actually happening?
Salt Lowers the Freezing Point of Water: When you sprinkle salt on ice, it melts slightly.
The Water Refreezes Quickly: Since the surrounding temperature is still cold, the melted water quickly refreezes.
The String Gets Trapped in the Ice: As the water refreezes, the string gets “locked” inside, making the ice stick to it.
It’s like a magic trick… but with SCIENCE!
What You’ll Need
You probably already have everything you need in your kitchen!
- A small bowl
- Cold water
- Ice cubes
- String (about 6 inches long)
- Salt (table salt works great!)
- Scissors
Optional: Add food coloring to the ice before freezing for a colorful twist!
How to Do the Sticky Ice Experiment
Step 1: Fill a bowl halfway with cold water.
Step 2: Add ice cubes to cover the surface of the water.
Pro Tip: The colder the water, the better! Warm water will cause the ice to melt too fast.
Step 3: Cut a piece of string (about 6 inches long).
Step 4: Lay the string gently on top of the ice cubes.
Step 5: Sprinkle salt generously over the ice and string.
Step 6: Wait for about 1–2 minutes. (Ask kids what they think will happen!)
Step 7: Carefully lift the string… BAM! The ice sticks to it like magic!
Ways to Make the Experiment Even More Fun
Try Different Types of Salt: Does rock salt work better than table salt?
Use Different Liquids: What happens if you use juice or soda instead of water?
Make It a Game: See who can lift the most ice cubes with their string!
Use Colored Ice Cubes: Freeze water with food coloring for a cool visual effect.

Final Thoughts
The Sticky Ice Experiment is a super easy, fun, hands-on way to introduce kids to science. It’s perfect for preschoolers, kindergarteners, and elementary students. Plus, it requires zero fancy equipment—just a bowl, some ice, salt, and string.
