The Science behind the Oobleck:

Prepare to unravel the scientific wonders of Oobleck, a substance that defies the rules established by Sir Isaac Newton and opens up a world of intriguing possibilities!

Non-Newtonian Fluid: Oobleck is classified as a “non-Newtonian” fluid, according to Science Learn,  meaning it doesn’t adhere to Sir Isaac Newton’s principles of how traditional liquids behave. Unlike Newtonian fluids, such as water or oil, that flow at consistent and predictable rates, Oobleck exhibits extraordinary properties that challenge conventional understanding.

Solid and Liquid Behavior: Oobleck has the remarkable ability to act as both a solid and a liquid, depending on the forces applied to it. When left undisturbed, Oobleck behaves like a liquid, flowing and dripping. However, when pressure is exerted on it, such as squeezing or stirring, it undergoes a fascinating transformation and behaves like a solid, resisting deformation.

 Suspension of Cornstarch: The key to Oobleck’s unique behavior lies in its composition. Oobleck is made by combining cornstarch and water. Unlike a solution where the particles dissolve uniformly, Oobleck is a suspension in which the grains of cornstarch are not dissolved but rather suspended and spread out in the water. These suspended particles give Oobleck its distinctive texture and properties.

Settling of Cornstarch: If you were to let an Oobleck mixture sit undisturbed for a while, you would observe an interesting phenomenon. Over time, the cornstarch grains would settle to the bottom of the container. This settling occurs due to gravity acting on the denser cornstarch particles, causing them to separate from the water.

Locking and Holding Shape: When you shape or apply force to Oobleck, something extraordinary happens. The cornstarch grains interact with each other and the water, creating temporary bonds that lock them together. These bonds give Oobleck its ability to hold its shape momentarily. However, once the force is removed, the bonds break, and Oobleck reverts to its liquid state, flowing and adapting to its surroundings.

The science behind Oobleck continues to intrigue scientists and researchers, as it defies traditional expectations and challenges our understanding of the behavior of fluids. By exploring Oobleck, we gain insights into the fascinating world of materials science, rheology, and the interplay between forces and matter.

So, dive into the captivating world of Oobleck, where its non-Newtonian properties and suspended cornstarch grains create an experience that is both scientifically intriguing and endlessly entertaining!

How to Store Oobleck:

Storing Oobleck is a simple process that allows you to keep it for future use.

Here’s a guide on how to store Oobleck properly:

  1. Prepare a container: Select a suitable container that is clean, airtight, and large enough to hold the amount of Oobleck you want to store. Options include plastic containers, glass jars with tight-fitting lids, or resealable plastic bags.
  2. Scoop the Oobleck: Use your hands or a spoon to gather the Oobleck from its current play surface or container. Make sure to scrape off any excess or stray particles.
  3. Transfer to the storage container: Place the collected Oobleck into the chosen storage container. If you’re using a baggie, squeeze out excess air before sealing it tightly. For containers with lids, ensure a secure closure to prevent any air or moisture from entering.
  4. Label and date: It’s helpful to label the container or baggie with the name and date to keep track of how long the Oobleck has been stored. This information can be useful if you want to use it again in the future.
  5. Store in a cool, dry place: Find a spot away from direct sunlight, heat sources, and excessive humidity to store your Oobleck. A cool pantry or cupboard works well. Avoid storing it in the refrigerator, as this can alter its texture and make it less enjoyable to play with.
  6. Check periodically: If you don’t plan to use the stored Oobleck for an extended period, it’s a good idea to check on it occasionally. Open the container or baggie, examine the texture, and ensure there is no mold or unusual odor. If any issues are detected, it’s best to discard the Oobleck and make a fresh batch when needed.

By following these steps, you can store your Oobleck properly, preserving its unique properties and ensuring it remains ready for future play. Enjoy the convenience of returning to the fascinating world of Oobleck whenever you desire!
