How to Choose the Best Thickening Agent for Your Needs?
Choosing the best oobleck thickening agent depends on the desired consistency and the materials available.
Consider the type of thickening agent, its ability to create the desired texture, and any potential safety concerns or allergies before making a decision.
Alternative Thickening Agents
Oobleck is a type of non-Newtonian fluid made by mixing cornstarch and water in a specific ratio, but there are other alternatives that offer similar thickening capabilities without relying on starch-based ingredients.
- Arrowroot powder is a natural thickening agent made from the root of the arrowroot plant. It has the advantage of being gluten-free and has a neutral taste, but can be more expensive compared to other thickening agents.
- Potato starch is extracted from potatoes and commonly used in cooking and as a thickening agent, including in oobleck. The advantages of using potato starch in oobleck are its ability to absorb water and create a gooey consistency, however, it tends to clump.
- Tapioca Powder, also known as tapioca starch, is a popular thickening agent made from the cassava root. It is an excellent gluten-free alternative to cornstarch and has a neutral flavor, making it ideal for use in a variety of recipes, including oobleck. However, it can become slimy if not used in the right proportions, and it may not provide the same level of viscosity as cornstarch.
- Baby Powder can be a goo alternative in a case, you run out of cornstarch but have cornstarch baby powder at home, you can prepare this version of oobleck and the whole room will smell like babies. It is important to note that only cornstarch-based baby powder will work to make oobleck. Talcum powder will not have the same thickening properties. Additionally, using baby powder to make oobleck can result in a strong, intense scent that may not be appealing to everyone.
Oobleck Ingredients without Cornstarch
- 1 part water
- 2 parts thickening agent (starch)
- Bowl for mixing
- Spoon for stirring
- Measuring cups
How to Make Non Newtonian Fluid with Alternative Thickening Agents
Choose a thickening agent.
Prepare the ingredients by measuring 1 part water and 2 parts thickening agent of your choice into a mixing bowl.
Mix the water and thickening agent together using a spoon until fully blended.
Keep stirring the mixture until it reaches a gooy texture. The duration required for the mixture to thicken may vary depending on the type of thickening agent in use.
Check the consistency of the oobleck by pressing a small amount between your fingers. If it feels solid when you squeeze it and then runs through your fingers like liquid when you let go, then you have successfully made oobleck.
Store the oobleck in an airtight container when you’re finished playing with it. If it starts to dry out, simply add a small amount of water and stir to bring it back to its original consistency.
Tips for Achieving the Right Consistency
To achieve the right consistency for oobleck, gradually add more thickening agent powder if the mixture is too watery, and add more water if it’s too thick, one teaspoon at a time. Continuously stir the mixture until the desired consistency is achieved.
If the oobleck is too runny, add a small amount of your thickening agent and continue to stir until you reach the desired consistency. If it is too thick, add a small amount of water and continue to stir until the oobleck reaches the desired consistency.

FAQ
Is Oobleck a Solid or a Liquid Substance?
Oobleck is a non-Newtonian fluid, meaning it has properties of both liquids and solids. When subjected to a steady force, it acts like a liquid, but when subjected to a sudden impact, it acts like a solid.
This makes Oobleck an interesting and unique material for sensory play and exploration.
How to Make Oobleck with Flour?
While flour may seem like a good thickening agent, you cannot make oobleck with them as it does not have the same thickening properties as cornstarch, the traditional thickening agent used to make oobleck.
Can I Save Hard Oobleck? How do I store oobleck?
It’s important to note that oobleck may lose its viscosity over time, so it’s recommended to use it within a few days of storage.
Hard oobleck can be stored in an airtight container in the refrigerator. It can be reused by adding a small amount of water to soften it and to help rehydrate the mixture.
Another thing to keep in mind is to avoid clogging pipes, it’s recommended to dispose of oobleck in the trash or let it dry out completely before throwing it away.
Is Oobleck Edible?
Oobleck is not toxic, but it is not recommended to eat it as it is not designed for consumption and may not taste good.
How to paint Oobleck?
To paint oobleck, you can add a few drops of food coloring or tempera paint to the mixture while making it. This will result in a colorful and visually appealing oobleck that is perfect for sensory exploration and play.
