The Science Behind Oobleck
Hello Challenger! Are you ready to dive into the fascinating world of oobleck? Before we begin, let’s discuss the science behind this strange substance. Oobleck is a non-Newtonian fluid that exhibits both liquid-like and solid-like properties. It gets its name from the Dr. Seuss book, Bartholomew and the Oobleck.
When a force is applied to oobleck, its viscosity increases, causing it to become more solid. Conversely, when the force is removed, the viscosity decreases, causing it to behave like a liquid. This unique behavior is due to the distribution of its ingredients, namely cornstarch and water.
Now that you know the science behind oobleck, let’s dive into how to make it!
Ingredients You’ll Need
To make oobleck, you’ll need the following ingredients:
| Ingredients | Quantity |
|---|---|
| Cornstarch | 2 cups |
| Water | 1 cup |
| Food coloring (optional) | A few drops |
Step-by-Step Instructions
Now, let’s get started with making your own oobleck:
Step 1: Add Cornstarch to a Bowl
Add 2 cups of cornstarch to a mixing bowl. Make sure that the bowl is large enough to accommodate the water and food coloring (if you decide to use it) as well.
Step 2: Add Water
Slowly pour 1 cup of water into the bowl with the cornstarch while stirring continuously. Keep stirring until the mixture is smooth and there are no lumps.
Step 3: Add Food Coloring (Optional)
If you want to add color to your oobleck, add a few drops of food coloring to the mixture and stir until the color is evenly distributed. Note that the color may be lighter than what you expect due to the cloudiness of the cornstarch mixture.
Step 4: Observe the Consistency
Once you’ve mixed your ingredients, observe the consistency of your oobleck. Note that it should be viscous and slightly solid-like when you touch it, and will probably look like a solid ball of dough when you scoop it.
Step 5: Experiment!
Now that you have your oobleck, experiment with it! Try to roll it into a ball, or make it ooze through your fingers. You can even try walking or running on top of it!
Step 6: Store It in an Airtight Container
When you’re finished experimenting, store your oobleck in an airtight container. Note that oobleck will dry out over time, so cover the container tightly to prevent this from happening.
Step 7: Dispose of It Properly
When you’re ready to dispose of your oobleck, make sure to dispose of it properly if you used food coloring in your mixture. Remember to pour it down the drain or flush it down the toilet.
