How To Make Cornstarch Chunks?

Cornstarch chunks, commonly referred to as non-Newtonian or oobleck, are a simple and entertaining scientific experiment that only requires a few basic materials.

Chunks of cornstarch have a special quality that allows them to function as both a firm and a liquid at the same time.

They make for a pleasant sensory experience and are a fantastic method to teach kids about science.

Chunks of cornstarch, also referred to as “water dough” or “water roux,” are a common ingredient in many desserts in China and Taiwan.

They are made by combining cornstarch and water and cooking the mixture over low heat until it thickens and takes on the consistency of dough.

A traditional Chinese dessert called Tangyuan is made with glutinous rice balls that are stuffed with sweet fillings and served in sweet syrup.

The dough is then formed into small chunks or balls and used in desserts like Tangyuan.

Chunks of cornstarch have a soft, chewy texture and a flavor that is neutral enough to go with a variety of dessert recipes.

They are flexible ingredients that can give a variety of desserts a distinctive texture and flavor.

Cornstarch pieces open up a lot of options, much like many other things in life.

They may be created in a variety of methods utilizing flavorings, spices, herbs, food coloring, a box, an oven, a microwave, and a freezer. The possibilities with cornstarch chunks are virtually endless.

The following is a step-by-step tutorial for making cornstarch chunks fast and easy:

Step 1: Gather Your Materials

The first step in making cornstarch chunks is to gather all the necessary ingredients.

Water, cornstarch and food coloring are required (optional). A sizable mixing basin and a spoon are also required, too.

Of course, there are countless ways to make cornstarch chunks; just use your creativity.

Why not, for example, add thyme and pepper? Thus, with only one piece, you can flavor and smooth a sauce at the same time.

Step 2: Mix Cornstarch and Water

Mix one part water and two parts cornstarch in a sizable mixing dish.

For instance, you should use two cups of cornstarch for every cup of water. Cornstarch and water should be combined until a thick, sticky material forms.

To thoroughly combine it, you might need to use your hands.

Step 3: Add Food Coloring (Optional)

You may add a few drops of food color to the mixture to give your cornstarch bits some color.

To ensure that the color is dispersed evenly, thoroughly incorporate the food coloring.

Step 4: Test the Consistency

Check the mixture’s consistency after combining the cornstarch and water.

A little extra water can be added if it is too thick. A little extra cornstarch can be added if it is too thin.

The consistency should be thin enough to flow when poured yet thick enough to keep its shape when squeezed.

Step 5: Make the Chunks

It’s time to create the cornstarch bits once you’ve reached the ideal consistency.

Shape the mixture into little bits or balls using your hands.

You can make them any size you want, but bear in mind that handling bigger chunks might be more challenging.

Step 6: Store the Chunks

After creating your cornstarch chunks, you can keep them in a plastic bag or another airtight container.

It is better to keep them in the refrigerator if you aren’t planning to utilize them right away. If they are properly stored, they can last for several days.

How To Make Cornstarch Chunks With Water?

This can be a tricky question since we always use water for making cornstarch chunks, but you should pay attention to the amount you use.

This is a quick recipe for making water and cornstarch chunks:


  • Cornstarch
  • Water


2 parts cornstarch and 1 part water should be combined in a mixing basin.

Create a thick, smooth paste by combining water and cornstarch.

As you add more water or cornstarch, the consistency will gradually become what you want. When squeezed together, it should be able to form chunks, but it should also be liquid enough to run and pour.

The mixture may be formed into a lump by scooping a teaspoon into your hand and firmly combining it.

Before starting to melt again, the chunk should feel firm and keep its shape for a brief period of time.

To create more bits of cornstarch, repeat the procedure.


  • To attain the proper consistency, try to avoid pouring too much water or cornstarch at once.
  • For added visual appeal, tint the mixture using food colors.
  • When the mixture dries, it becomes slick and difficult to clean up spills, so wipe them up with a moist towel.

How To Make Cornstarch Bricks In The Oven?

Of course, heating up the renowned cornstarch cubes in the microwave is the quickest method.

Despite simplicity and peace of mind, cornstarch chunks won’t be as crispy when prepared in the microwave.

You need patience and heat to drain all the water included in the starch granules in order to do that.

While it may not be apparent, this powder does include a very little amount of water.

What you’ll need:

  • 450 grams of cornstarch (about a Pound)
  • a vacant box (can use the cornstarch box)
  • Metalized foil
  • If you would want any seasonings or additions

Examine the simple steps:

Add any spices and cornstarch to the box.

Form a block with the cornstarch by pressing firmly and forcefully. Condensing the powder and removing the air are the objectives here. Use a brick or any large item you have at home if necessary.

After forming the brick, gently transfer it to the tinfoil and tightly cover it. It’ll appear to be a silver brick.

Put for roughly two hours at 375°F in a preheated oven. Open the oven and check it every half an hour. Should be burnt, but should be more solid than before.

Place in the freezer for a minimum of 4 hours.

That’s it; cut the block into pieces and have fun.

How To Make Cornstarch Chunks Without Oven?

Making these chunks involves combining cornstarch and water, heating it slowly over low heat until it thickens and takes on the consistency of dough.

Here’s how you can produce cornstarch chunks without an oven:


  •   50 ml of cornstarch
  •   1/2 cup water


In a small pan, mix the cornstarch and water until well blended. To completely combine it, you might need to use your hands.

Cook the mixture over low heat, stirring regularly with a wooden spoon. The mixture will begin to thicken and take on the consistency of dough. Maintain swirling to avoid lumps from developing.

When the blend has thickened sufficiently that you just can see the foot of the skillet as you mix, turn off the warm.

Allow the blend to cool down for many minutes until it’s cool sufficient to handle together with your hands.

Take a small amount of the blend and roll it into a ball or any desired shape. On the off chance that the blend is as well sticky, you’ll be able softly to clean your hands with cornstarch.

Rehash the method until all the blend is utilized.

The cornstarch chunks can presently be utilized in different sweets, such as Tangyuan, a conventional Chinese dessert made with glutinous rice balls stuffed with sweet fillings and served in sweet syrup.

Note: The cornstarch chunks will end up firm as they cool down. They can be put away in a hermetically sealed holder within the cooler for up to a week.

How To Make Microwave Cornstarch Chunks?

The invention of the microwave helped all of us live better lives and facilitate faster cooking.

This amazing equipment makes it possible for you to quickly create the cornstarch chunks you want.

Making cornstarch chunks in the microwave is the easiest and quickest way. You’ll do this along with your kids as a family project.

The kids will cherish this. Additionally it is an perfect way to spend quality time together with your children.

Making these cornstarch bricks at home is a quick and easy science experiment that only requires a few simple items.

Here is a step-by-step tutorial for making bricks out of cornstarch.


  • Cornstarch 1 cup
  • A half-cup of water
  • The colorant (optional)
  • Spoon
  • Mixing bowl
  • Safe for the microwave container
  • Spray cooking
  • Wax paper


Mix 1 cup cornstarch and 1/2 cup water in a mixing bowl. Blend the ingredients until the cornstarch is completely dissolved and the mixture is smooth.

Mix a few drops of food coloring into your bricks if you wish to give them color.

Stirring every 30 seconds, place the mixture in a microwave-safe container, and heat for 2-3 minutes. Be sure to whisk the mixture thoroughly to avoid lumps because it will thicken as it boils.

Remove the mixture from the microwave once it has thickened and solidified into a mass, then wait a few minutes for it to cool.

A sheet of wax paper should be greased with cooking spray and set down on a flat surface.

Place the cornstarch mixture onto the wax paper after carefully removing it from the container.

To form the mixture into brick-sized blocks, use your hands.

Overnight or for several hours, let the bricks dry. When they dry, they will grow harder.

The bricks can be stacked and used for building and experimentation once they have dried.

Note: If handled roughly, cornstarch bricks may crack or crumble as they are not very sturdy. They work well for straightforward construction jobs and tests.
