Make some incredibly cool “Cloud Dough” at the art center today. This easy no-cook dough requires just 2 ingredients: cornstarch and hair conditioner. Easy enough! Mix equal parts together in a bowl. There is no cooking required and students can get their hands messy while helping to make it. This hands-on preschool activity is fun all year long. This is a great science experiment for kids. They can pretend it is snow or sand. Have fun exploring with this sensory activity.
