4 Different Methods to Make Cornstarch Chunks

01: How to Make Cornstarch Chunks With Water?

Below I’ll be adding the process of making cornstarch chunks with water. So, keep on reading.

Required Equipment

First, make sure you have all the things you’ll need. You’ll need

  • A large size bowl and a spoon
  • Water (1 Cups)
  • Cornstarch (2 Cups)
  • Food coloring (Optional).

Additionally, you can add things like thyme and pepper to your chunks. It should make them more special.

Step 1: Mix Cornstarch and Water

First, take a big bowl and put one cup of water and two cups of cornstarch in it. Now, mix them together until it turns into a thick, sticky substance. I suggest using your hands to mix it really well.

Step 2: Add Color (If You Want)

If you want your cornstarch chunks to have color, you can add a few drops of food coloring. Mix it properly and make sure that the color spreads evenly.

Step 3: Check the Thickness

After you’ve mixed the cornstarch and water, check if the thickness is right or not.

If it’s too thick, you can add a little more water. If it’s too thin, add a bit more cornstarch. It should be thin enough to flow when you pour it but thick enough to hold its shape when you squeeze it.

Step 4: Make the Chunks

Now, it’s time to shape your cornstarch into chunks. To do it, use your hands to make little bits or balls. You can decide how big or small you want them to be. Keep in mind that making bigger chunks might be a bit challenging.

Step 6: Store the Chunks

Now it’s time for storing. The best way to store cornstarch chunks is by using an airtight container or plastic bag.

If you don’t have any plan with the chunks, then keep them in the refrigerator. By properly storing them you can make them last for several days.

  3. Now, let the mixture cool down for a few minutes until it’s cool enough to handle with your hands.
  4. Take a small amount of the mixture and shape it into a ball. You can also give it any shape you like. If the mixture is too sticky, you can lightly dust your hands with cornstarch to make it easier to handle.

How to Make Cornstarch Chunks Fast?
Making Cornstarch Chunks

The fastest way to make cornstarch chunks is to microwave them. This method takes only 2-3 minutes, compared to the 1 hour required to boil cornstarch chunks. So, the first thing you need is the right temperature. If the cornstarch is cold, it will take longer to form into chunks. To help it bind perfectly, add some water to the cornstarch.

Mix cornstarch and water in a bowl and stir until the cornstarch is completely dissolved. Then, refrigerate the mixture for about 15 minutes to chill it. Once chilled, take small amounts of the mixture and roll them into balls.✨

How Long Does It Take to Make Cornstarch Chunks?

The time it takes to make cornstarch chunks depends on the method you use.

  • Oven: 30-60 minutes, depending on the temperature and the size of the chunks.
  • Microwave: 2-3 minutes, checking frequently to avoid burning.

Another factor that can affect the cooking time is the amount of water you add to the cornstarch. If you add too much water, the cornstarch chunks will take longer to cook. If you add too little water, the cornstarch chunks will be dry and hard.

Here is a tip for shortening the cooking time: Microwave the cornstarch mixture for 1-2 minutes before forming it into chunks. This will help to pre-cook the cornstarch and reduce the overall cooking time.

Please note that cornstarch chunks can be a choking hazard, so it is important to supervise children while they are eating them.

How to Make a Cornstarch Brick?

Hey foodie friends! ✨ Ever thought about making your own cornstarch brick? It’s a blast, I’m mentioning here two awesome ways to do it, depending on your vibe:

Method 1: Simple Cornstarch Brick (Oobleck)

For this playful method, mix up equal parts cornstarch and water in a bowl. Start small and add more until you get a thick, gooey consistency that holds its shape but flows when pressed. Give it a quick knead, and voila! Your cornstarch brick is ready for some solid-yet-liquid fun.

Method 2: Air-Dry Cornstarch Clay Brick

If you’re into more permanent, crafty vibes, try this method. Combine 1 cup cornstarch, 1/2 cup white glue, and 1-2 tablespoons glycerin (optional, but it adds flexibility) in a mixing bowl. Throw in some food coloring if you’re feeling fancy. Pack the dough into a mold, let it air dry for 24-48 hours, and boom! Your cornstarch clay brick is ready for personalization.

A couple of friendly reminders:

  • Adult supervision is a good call for both methods, especially for our little creators.
  • Please resist the urge to snack on your cornstarch bricks; they’re for play and crafting only.
  • These bricks aren’t fans of water, so keep them dry to avoid a gooey situation.
  • Air-dried cornstarch clay bricks are sturdy but not indestructible, so handle with a bit of TLC.
  • Hope you have a blast making and playing with your cornstarch bricks!
