Have you ever ever questioned if one thing might act like each a liquid and a stable on the similar time? Sounds unimaginable, proper? Nicely, with a easy recipe, you’ll be able to create a tremendous substance referred to as Oobleck that does simply that! Oobleck is a “non-Newtonian fluid,” which means it behaves like a stable once you apply strain however turns again right into a liquid once you launch it. It’s a enjoyable and messy experiment that you would be able to attempt at residence or within the classroom. Plus, simply click on the button beneath to seize your free recording sheet to share this Oobleck experiment together with your class. Let’s get began!
What does the Oobleck experiment educate?
The Oobleck experiment is a superb instance of non-Newtonian fluids and the way supplies can react beneath totally different stress situations. As a result of Oobleck doesn’t comply with the same old guidelines of liquids, it may be a number of enjoyable to your class to expertise this anomaly.
How To Make Oobleck Video
This video reveals detailed step-by-step directions in a visible option to grasp the experiment.
Supplies Wanted
If you wish to know tips on how to make Oobleck, first you want:
- 2 cups cornstarch
- 1 cup water
- Meals coloring (any colour you want—inexperienced is tremendous enjoyable!)
- A mixing bowl
- A spoon (or simply your fingers)
- A measuring cup
The way to make Oobleck step-by-step:

2. Put together the coloured water.
Subsequent, seize your water and add a couple of drops of meals coloring. This step is elective, nevertheless it makes the Oobleck additional enjoyable and colourful! Stir the water gently till the meals coloring is absolutely dissolved.
3. Mix the cornstarch and water.
Slowly pour the coloured water into the bowl of cornstarch. Do that slightly at a time whereas mixing with a spoon. As you combine, you’ll discover the feel begin to change. It would look slightly lumpy at first, however preserve stirring.
4. Get hands-on.
As soon as the combination begins to come back collectively, use your fingers to knead and blend the Oobleck. You’ll need the consistency to be good: stable once you press it however liquid once you launch it. If it’s too thick, add a tiny bit extra water. If it’s too runny, add extra cornstarch.
5. Play and discover.
Now for the enjoyable half! Strive totally different experiments together with your Oobleck. Squeeze it, poke it, roll it right into a ball, or faucet it rapidly. The extra strain you apply, the extra stable it turns into. While you calm down your fingers, it flows like a liquid. Oobleck is a non-Newtonian fluid, which implies it doesn’t comply with the traditional guidelines of liquids. It’s stable when pressed and liquid when unstressed. Science is fairly cool, proper?
6. Clear up.
Oobleck can get fairly messy, so ensure you do that experiment in a spot that’s straightforward to scrub up. When you’re finished enjoying, simply let the combination dry out, then sweep it up or vacuum it.
What can we be taught with Oobleck?
● Pace vs. strain: What occurs once you transfer your fingers by the Oobleck slowly versus rapidly? Strive it out and see how the Oobleck reacts.
● Totally different shapes: Strive rolling the Oobleck right into a ball and see if you can also make it bounce or keep in form for a couple of seconds.
That’s it! Now you’ve created your very personal Oobleck and discovered about non-Newtonian fluids. Oobleck is an superior option to discover the properties of solids and liquids in a enjoyable, hands-on manner. Plus, it’s an ideal excuse to get slightly messy and inventive. Bear in mind, science is all about curiosity and experimentation, so preserve exploring and have enjoyable.
