DIY Cornstarch and Dish Soap Kinetic Sand


Fun, sensory play made simple!

Looking for an easy, budget-friendly, and super fun sensory activity? This homemade Kinetic Sand made from cornstarch and dish soap is a fantastic way to bring hands-on play into your home without breaking the bank or needing specialty supplies. Kids love it, and grown-ups will enjoy how simple it is to make and clean up.

This moldable, squishable material behaves like a hybrid between play dough and sand. It’s perfect for building, sculpting, and sparking creativity—plus it smells great if you use scented dish soap!


🛒 What You’ll Need

  • 1 cup cornstarch
  • ½ cup liquid dish soap (any scent or color works)
  • Food coloring (optional—for fun colors)
  • Mixing bowl & spoon
  • Airtight container (for storing leftovers)

👩‍🔬 Step-by-Step Instructions

1. Mix the Base:
Start by adding 1 cup of cornstarch to a medium mixing bowl.

2. Add Dish Soap Slowly:
Gradually pour in ½ cup of liquid dish soap, stirring as you go. You’re aiming for a crumbly texture that holds together when squeezed.

3. Knead It:
Once it’s mostly combined, switch to kneading the mixture with your hands. It should come together into a soft, slightly sticky dough that’s easy to mold.

4. Add Color (Optional):
Want to jazz it up? Add a few drops of food coloring and knead until the color is evenly distributed. Be careful—some food colorings may stain hands, so gloves are a good idea if you’re worried.

5. Play & Store:
Let the fun begin! Scoop it, mold it, flatten it—whatever you can imagine. When you’re done, store the sand in an airtight container to keep it from drying out.


🌟 Tips for Success

  • Too dry? Add a tiny bit more dish soap.
  • Too sticky? Sprinkle in more cornstarch.
  • Make it themed: Use seasonal colors or add a bit of glitter for a magical touch.
  • Add tools: Try playing with cookie cutters, spoons, or small toy molds for extra fun.

💡 Why It Works

Cornstarch gives the kinetic sand its powdery, moldable structure, while dish soap adds stretch and stickiness—kind of like slime meets sand. The result is a fascinating sensory material that kids (and adults!) can’t resist.


🧼 Easy to Clean Up

Don’t worry—this version of kinetic sand won’t leave gritty messes everywhere. It sticks together well and wipes up easily with a damp cloth or paper towel.
