Why Baking Soda?
Adding baking soda to oobleck can help it last longer and prevent mold growth. Baking soda is an alkaline substance that can help balance the pH of the oobleck, making it less hospitable to mold and bacteria. Additionally, baking soda can react with the acid in the food coloring (if used) to create more vibrant colors.
Expert Opinion
According to Dr. Karen K. Lee, a pediatrician and founder of the non-profit organization Healthy Children Project, Playing with oobleck can help children develop fine motor skills, encourage creativity and imaginative play, and provide a sensory experience that can be calming and soothing.
My Experience
I’ve made oobleck with and without baking soda, and I have to say that adding baking soda definitely makes a difference. The oobleck lasts longer and doesn’t get moldy as quickly. Plus, the baking soda seems to make the oobleck feel smoother and silkier to the touch.
