Measure all the ingredients precisely with measuring cups that you fill up to the top and level up.
In a medium mixing bowl, add Conditioner or lotion, liquid food coloring if used, and corn starch.
Stir with a spatula at first. It will form crumbly sand, that's normal, and kids love this part. Dig your hand in the mixture, squeeze and run the ingredients together to form a dough. It will look like damp sand that holds together as you apply pressure on it then crumbles again.
After 1 minute of kneading the dough, it should form a moldable dough similar to classic playdough, but that breaks much more easily into pieces.
Play with it as is or crumble in a plastic tub to create a sensory bin.
