Measure the cornstarch into your bowl and feel its cool, powdery texture between your fingers.

Add two tablespoons of dish soap. Stir slowly with the spoon and watch the cornstarch take on a creamy sheen.

Test the mixture's texture by pressing a small amount between thumb and forefinger. If it feels crumbly, add a half teaspoon of warm water and stir again.

Continue adding water, a few drops at a time, until the dough becomes slightly sticky but not wet.

Scoop the mixture onto a clean surface and knead gently.

If you want color, add a single drop of food coloring to the center of the dough and fold until evenly tinted.

If the dough feels too sticky, sprinkle a pinch of cornstarch and knead it in.

When the dough forms a cohesive, slightly bouncy ball, allow it to rest for five minutes.

Use the dough in calm play or sensory exploration.

Store the dough in a sealed container at room temperature.
