How To Make Oobleck – A Fun and Easy Science Experiment at Home
If you’ve ever wanted to try a cool science experiment that’s fun for both kids and adults, making Oobleck is the perfect choice! Oobleck is a fascinating non-Newtonian fluid, meaning it behaves like both a solid and a liquid depending on how you handle it. Let’s dive into how to make Oobleck at home with simple ingredients you already have in your kitchen.
What Is Oobleck?
Oobleck gets its name from a Dr. Seuss book called Bartholomew and the Oobleck. It’s made from just cornstarch and water, creating a unique substance that hardens when you press it but flows like a liquid when you let it rest. This simple science experiment is a great way to learn about viscosity and states of matter.
Ingredients You’ll Need
There are just two essential materials needed to make your own Oobleck:
One cup of cornstarch
Half a cup of water
Food coloring is optional, but it can lend a playful splash of color.
Detailed Instructions for Making Oobleck
To make Oobleck in a matter of minutes, simply follow these steps:
1. Fill a basin with cornstarch.
To begin, put your cornstarch in a medium-sized bowl.
2. Slowly add water.
Add water gradually while stirring constantly. Mix gradually until it begins to thicken, rather than dumping it all in at once.
3. Stir till it feels just perfect.
When you can tap it and it feels solid, but when you release the pressure, it drops like a liquid, you know you’ve made Oobleck.
4. You can add color.
Add a few drops of food coloring for a colorful, striking finish. If you want it to look like slime, green is popular!
How To Know Your Oobleck Is Perfect
-
Too thick? Add a bit more water.
-
Too watery? Add more cornstarch.
You’ll know you’ve got it right when you can roll it into a ball that melts in your hand seconds later.
Fun Ways To Play With Oobleck
-
Punch it and watch it harden instantly.
-
Let it flow through your fingers.
-
Try making it dance on a speaker using sound vibrations!
How Oobleck Can Be Cleaned
Oobleck is easy to clean:
It can clog pipes, so don’t put it down the drain.
After letting it dry, dispose of the solid residue in the garbage.
Use a cloth and warm water to clean surfaces.
Oobleck’s Scientific Basis
A non-Newtonian fluid is oobleck. This indicates that the viscosity, or thickness, varies with the amount of pressure applied. It behaves like a solid when you push or strike it because the cornstarch particles bind together. The particles split and take on the characteristics of a liquid when you allow it to rest.
