How Do You Make Oobleck With Borax?
Oobleck is a wonderfully messy craft project that doubles as a great scientific learning experience. Taken from Dr. Seuss’s book, “Bartholomew and the Oobleck,” about a similar slimy goo that covers an entire kingdom, oobleck is a jelly-like substance that acts as both a solid and a liquid. It’s easy to make and even more fun to squish, smash and squeeze. Oobleck is non-Newtonian, which means when you touch it with a small amount of pressure, it acts like a liquid, but when you use a greater amount of force, it acts like a solid. For example, you can stick your finger slowly into oobleck, but you can’t quickly swirl your finger around in it. The recipe below calls for liquid Borax, which you can find in the laundry detergent section at your local grocery store. Cover your work space and the floor below it with a layer of newspaper. Wear old clothes or a smock in case you splash some of the oobleck on yourself. Pour 1/2 cup water into your large mixing bowl or disposable plastic contain
