The Peppermint Oobleck Activity is an exciting sensory experience that encourages fine motor development, sensory learning, and hours of fun! This DIY activity is a safe and interactive hands-on experience that teaches children about states of matter, pressure, and more. Peppermint Oobleck engages the senses of touch and smell, encouraging children to interact with the Oobleck on multiple levels.
How Does Peppermint Oobleck Work?
A simple mixture of cornstarch and water creates Oobleck, a substance that transforms from a liquid to a solid with the simple addition of pressure. Pressure-dependent substances such as Oobleck are known as non-Newtonian fluids. By applying pressure to the mixture, the viscosity (thickness) increases, making the Oobleck feel hard and solid. When you run your hands slowly through the Oobleck, the mixture feels like a smooth liquid because the cornstarch particles are more fluid and movable. As children get their hands directly into the mixture, they will quickly learn how the pressure of their hands and movement throughout the mixture can turn the Oobleck from a solid to a liquid and then back again.
Why Are Fine Motor Activities Important?
The addition of peppermints into the Oobleck mixture provides a unique outlet for developing fine motor skills. Have children use tweezers or other tools to move and pluck the peppermints out of the Oobleck. This fine motor activity helps to develop the muscles and coordination necessary for children to complete important tasks such as holding pencils, writing, and buttoning clothes. The peppermints also create beautiful swirls of red throughout the Oobleck and release a wonderfully minty scent in the air!
