Shaving Cream Water Experiment: A Fun and Colorful Science Activity for Kids
The shaving cream water experiment is an engaging and visually delightful activity that introduces children to basic scientific concepts in an exciting way. Ideal for home, school, or outdoor settings, this experiment uses everyday household materials to demonstrate how different substances interact. The vibrant visuals created by the food coloring dripping through the shaving cream into the water below mimic the behavior of rain falling from clouds—making it a perfect blend of fun and learning.
This activity not only entertains but also educates, showing children how water density and gravity work, using colorful visuals to represent weather phenomena. For parents and educators looking for a hands-on, mess-friendly science project, this is a go-to option.
Ingredients
To carry out this experiment, you will need the following materials:
- Water
- Shaving cream
- Blue food coloring
Each ingredient is likely already in your home, making this craft accessible and budget-friendly.
Instructions
- Fill the Container
Begin by filling a clear plastic jug or glass about two-thirds full with water. This will act as your “sky” in the demonstration. - Add the Shaving Cream
Next, apply a thick and fluffy layer of shaving cream on top of the water. This layer represents the clouds and creates a barrier between the water and the food coloring. - Add Food Coloring
Gently drop blue food coloring over the surface of the shaving cream. As the drops sit momentarily on the foam, they will eventually begin to seep through and fall into the water, creating a mesmerizing rain-like effect.
Watch as the color slowly descends, mimicking the appearance of rainfall from clouds into a body of water.

Benefits of This Craft
This simple experiment provides several educational and sensory benefits:
- Teaches Scientific Concepts
Children get a basic understanding of weather systems, specifically how rain is formed when clouds become saturated. - Encourages Critical Thinking
Kids will naturally begin to ask “why” and “how” questions during the activity, helping to spark curiosity and deeper learning. - Enhances Motor Skills
Squeezing shaving cream and adding drops of food coloring require fine motor control, perfect for younger learners. - Boosts Creativity
You can switch up the food coloring for a rainbow effect, turning it into an artistic as well as scientific endeavor. - Promotes Focus and Patience
Since the effect takes a few seconds to start, children learn the value of observation and waiting for results.

Tips
- Use a deep and wide clear container to better observe the full descent of the color.
- Experiment with different colors for a rainbow or stormy effect.
- Try timing the descent of the food coloring for a more advanced experiment.
- Add pipettes or droppers for more control when kids apply the food coloring.
- Place the container against a white background to better view the color transformation.
What Does It Look Like?
While the experiment doesn’t involve taste (as it’s not edible), the visual impact is striking. The appearance of the blue food coloring dripping through the fluffy white shaving cream and diffusing into the water is both calming and captivating. It closely resembles rain falling from clouds into the ocean or a lake. The color swirling as it descends adds a magical touch, often referred to as “a science cloud show in a jar.”
How to Store
Since this is a single-use craft, it’s not intended for long-term storage. However, here’s what you can do post-experiment:
- Dispose of the used shaving cream and water safely in the sink.
- Wash and dry the container if you plan to reuse it for other activities.
- Store leftover materials like food coloring and shaving cream in a cool, dry place for future experiments.
The shaving cream water experiment is more than just a fun activity—it’s an engaging introduction to science and weather that can be conducted with minimal materials and effort. Whether you’re a parent looking for an educational weekend activity, or a teacher seeking a hands-on classroom demonstration, this project offers the perfect balance of visual appeal and learning.
It’s crafts like these that make science come alive for kids, showing them that even everyday items can help explain the world around them.
FAQ
What age group is this experiment suitable for?
This activity is safe and appropriate for children aged 3 and up, with adult supervision.
Can I use something other than shaving cream?
Not really—shaving cream provides the right consistency and texture for the “cloud” effect.
What if the food coloring doesn’t drip through?
Try adding a bit more food coloring or gently pressing the foam with a dropper. Avoid mixing the shaving cream too thick.
Can I use liquid watercolors instead of food coloring?
Yes, liquid watercolors can also work well for this experiment.
Is it safe if a child touches or accidentally ingests it?
While this is not edible, the ingredients are generally non-toxic. Still, ensure children avoid putting any part of the craft in their mouths and wash hands after the activity.
How long does the experiment take?
The visual effect begins within a few seconds and can last for several minutes as the color continues to fall and diffuse.
