How do you explain oobleck to preschoolers?
Oobleck is a mixture of a solid (corn starch) suspended in a liquid (water). Oobleck behaves like a solid when force is acted on it quickly. This is because the pressure forces all the particles of corn starch together and they behave like a solid.
What experiments can you do with oobleck?
5 Fun Oobleck Experiments

What do children learn from making oobleck?
It is also a fantastic way to introduce children to basic concepts of matter. In addition to learning about science concepts, Oobleck is also great for the development of fine motor skills as children work and strengthen their little hand muscles while engaged in sensory play.
What is oobleck science?
Oobleck is a non-Newtonian fluid, a term for fluids that change viscosity (how easily they flow) under stress. When you run your fingers slowly through cornstarch and water, it acts like a liquid, but apply rapid force, and it solidifies, bends and even tears.
What is the science behind the Oobleck?
Oobleck is a suspension of starch in water. The phenomenon is called shear thickening and it basically means particles in a dense suspension resist further compression in the direction of shear. When oobleck is at rest, the high surface tension of water causes water droplets to surround the starch granules.
Does oobleck have any uses?
Thus, the application provides a system of temporarily fixing potholes by filling them with bags of oobleck (or other non-Newtonian fluids). When the bag is placed in the pothole, the oobleck has time to act like a fluid and fill the hole.
How do you make an oobleck science experiment?
- Ask student to create a testable question (a hypothesis).
- Put 1 cup of water in a bowl and gradually add the cornstarch to it.
- Mix and blend very well.
- If desired, mix in a few of drops of food coloring.
- Bonus: Use a large plastic bin or tub to make a big batch of Oobleck.
