OOBLECK RECIPE

Let’s get right to the oobleck recipe for our Bartholomew and the Oobleck activity. Head to the kitchen, open the pantry and be prepared to get a little messy. We added small plastic figurines to this Dr Seuss oobleck activity to play along with the book. LEGO works well too.

YOU WILL NEED:

2 cups cornstarch
1 cup water
Food Coloring (optional)
Small Plastic Figurines or Items (optional)
Baking Dish, Spoon
Book: Bartholomew and the Oobleck by Dr. Seuss

HOW TO MAKE OOBLECK:

Oobleck is a combination of cornstarch and water. You will want to keep additional cornstarch on hand if you need to thicken the mixture. Generally, the oobleck recipe is a ratio of 1:2, so one cup of water and two cups of cornstarch.

STEP 1: In your bowl or baking dish, add the cornstarch. You can start mixing the oobleck in a bowl and then transfer it to a baking dish if you prefer.

STEP 2: If you want to give your oobleck a color such as green, add food coloring to your water first. Remember that you have a whole lot of white cornstarch so you will need a good amount of food coloring if you want a more vibrant color.

STEP 3: You can start mixing up your oobleck with a spoon, but I guarantee you are going to need to get your hands in there at some point during the mixing process.

THE RIGHT OOBLECK CONSISTENCY

There is a gray area for the right oobleck consistency. First, you don’t want it to be very crumbly, but you also don’t want it to be very soupy either. If you have a reluctant kiddo, hand them a spoon to start! Let them warm up to the idea of this squishy substance. Never force them to touch it though.

The perfect consistency for oobkeck is when you can pick up a clump in your hand, form it into a ball of sorts, and then watch it flow like a liquid back into the pan or bowl.

Once you have your oobleck mixed to the desired consistency, you can add your accessories as desired and play!

THE SCIENCE OF OOBLECK

Can you imagine oobleck falling from the sky as happens in Bartholomew and the Oobleck? What would it feel like to have goo all over you? Would you like that or not?

What is oobleck?

Oobleck is a fun substance to play with which is made from cornstarch and water. It’s a bit messy too!

It is a great example of a mixture! A mixture is a material made up of two or more substances combined together to form a new material and that can be separated again. Do you think the oobleck mixture could be separated into cornflour and water again? How?

Try leaving a tray of oobleck out for a few days. What happens to the oobleck? Where do you think the water has gone?

This oobleck activity is also a great way to explore the properties of liquids and solids, know as the states of matter. Here we are combining a liquid and a solid, but the mixture doesn’t become one or the other. A solid has its own shape whereas a liquid will take the shape of the container it is put into. Oobleck is a bit of both!

That’s why oobleck is called a non-Newtonian fluid. This means it is neither a liquid nor a solid but has properties of both! You can pick up a clump of the substance like a solid and then watch it ooze back into the bowl like a liquid. Touch the surface lightly and it will feel firm and solid. If you apply more pressure, your fingers will sink into it like a liquid.

Is oobleck a solid?

Or is oobleck a liquid?

Did you know that cornstarch is a polymer? Polymers have long chains that make them up (like the glue used in slime). When these chains get all tangled up with one another, they create more of a solid!

OOBLECK EXPERIMENT

Want to experiment with viscosity? Easy, change the ratio of water to cornstarch! Viscosity is the physical property of fluids and how thick or thin they are and including how they flow.

What happens when you add more cornstarch? Does the oobleck become thicker or thinner?
What happens when you add more water? Does it flow faster or slower?

Can you make oobleck without cornstarch?

You could try making oobleck with flour, powder, or baking soda and compare the similarities and differences.

We tried an oobleck experiment of our own using just cornstarch and glue. Find out what happened —> OOBLECK SLIME
