Step-by-step Instructions

Mixing the Ingredients:

To make cornstarch bricks, start by mixing together 4 cups of cornstarch and 2 cups of water in a large bowl. Combine the ingredients thoroughly until the mixture reaches a thick, smooth consistency.

Filling the Mold:

Next, fill a brick-shaped mold with the cornstarch mixture. Press the mixture firmly into the mold, ensuring it is evenly distributed.

Allowing the Bricks to Dry:

Leave the filled mold in a cool, dry area for about 24-48 hours. This allows the cornstarch bricks to dry and harden. Avoid moving or disturbing the mold during this time.

Once the bricks have fully dried, carefully remove them from the mold. Now, you have homemade cornstarch bricks that are ready for use in various crafting projects or science experiments.

Testing And Usage

Cornstarch bricks are a sustainable alternative to traditional building materials. Strength and durability testing has demonstrated that these bricks are comparable to concrete in terms of load-bearing capacity. Their application in constructing eco-friendly structures has shown promising results, leading to the potential for widespread use in the construction industry.
