What are some fun and educational ways to engage children in a hands-on oobleck activity?

One fun and educational way to engage children in a hands-on oobleck activity is to have them mix cornstarch and water together to create the oobleck substance. Encourage them to explore the unique properties of oobleck by squeezing it, rolling it into a ball, and watching it change from a solid to a liquid. You can also add food coloring to make it more visually appealing and incorporate a discussion about non-Newtonian fluids and the science behind oobleck.
