What you'll need:
- 1/2 cup shampoo (those small free sample bottles are perfect for this)
- 1/4 cup cornstarch
- food coloring [optional]
- about 6 tablespoons of water
In a large bowl, add the shampoo and cornstarch and mix until smooth.
Add a few drops of the food coloring, if desired, and mix.
Add one tablespoon of water at a time, slowly, and stir between each.
Use hands to knead the mixture for a couple minutes until it reaches the desired consistency.
