How to Make It – Step by Step
1. Gather Your Ingredients
Start with one color at a time. Measure 1/2 cup water, 1/4 cup soap, and a few drops of food coloring into a mixing bowl or blender.
2. Blend Until Fluffy
Mix on high for 1–2 minutes until thick, foamy peaks form. Keep a close eye—it fluffs up quickly!
3. Scoop and Repeat
Transfer the foam to your sensory bin. Rinse the bowl and repeat with different colors—red, orange, yellow, green, blue, and purple—to create your rainbow.
4. Time to Play!
Let kids dig in! Encourage scooping, swirling, painting, or just exploring with fingers. Add foam letters, toys, or kitchen tools for extra fun.
Tips & Fun Variations
- Add Sparkle: A pinch of glitter in each foam color creates magical shimmer.
- Scent the Foam: Use a drop or two of child-safe essential oils (like lavender or orange) for a lovely sensory touch.
- Theme It: Try galaxy colors with dark blues and purples or pastel blends for spring.
Clean-Up Made Simple
One of the best parts? Clean-up is a breeze. Most of the foam rinses away with warm water, and any remaining soap actually helps clean your tub or tray!

It’s best used fresh, but you can make it a few hours ahead and keep it in an airtight container.
