A liquid that exhibits properties of both a solid and a liquid; does it exist on Earth? “Science Guy” Jason Lindsey with Hooked on Science says it does, and all you need are a few supplies from around the house to create your own batch. Make sure an adult supervises with this, and all experiments.
11⁄4 cup of corn starch
3⁄4 cups of water
1 sturdy stirring spoon
Green food coloring
1 mixing bowl
STEP 1: Add green food coloring to the water.
STEP 2: Slowly add the corn starch to the water.
STEP 3: Adjust the amount of cornstarch to reach the desired consistency. Add more corn starch to achieve a thicker mixture. Use your hands to feel the substance.
Oobleck is considered a non-Newtonian fluid, which means it can exhibit properties of both a solid and a liquid. This is due to the nature of corn starch, which is a natural polymer — a chemical compound made by linking smaller molecules in a long, repeating chain.
