How to make oobleck without cornstarch

Flour (standard wheat flour) will not make Oobleck. Once combined with water, it will create a paste instead, which is how a simple homemade glue is actually made. The usual ingredient is cornflour but you can also use arrowroot powder or tapioca powder instead, see: How to Make Oobleck without Cornstarch.

Arrowroot Oobleck Recipe

After some back and forth we found 2 1/4 cups of arrowroot flour and 2/3 cup of water gave us a nice non-Newtonian Fluid that was similar in consistency to our standard cornstarch oobleck. Nicely solid under pressure. But remove that pressure and it liquefies and pours.

“It’s a fun thing to make for both kids and adults.” Oobleck is cornflour and water. Slowly add 1.5 to two parts cornflour, stirring constantly. Starch particles become suspended in water — but too much water will create liquid.

Start with the vinegar in a bowl and add a few drops of food coloring. Start adding the cornstarch to it a bit at a time. Follow all of the instructions for the regular oobleck until you have a good consistency.

Arrowroot powder, tapioca powder, and potato starch are all direct substitutions. To make your oobleck look more interesting, add some food coloring into the water. Start with 2 to 3 drops, then add more until you get the color you want.

Mix 2 cups of cornstarch to 1 cup of water into a bowl. Mix the cornstarch and water until your oobleck is formed. Tip: If you would like to color your oobleck, add your food coloring to your water and then mix with the cornstarch. Just keep experimenting until you get the consistency of oobleck.

Luckily, the gooey substance is not toxic, but it probably won’t taste good since it’s just cornstarch and water. As one individual pointed out on Yahoo Answers, while eating oobleck may not be poisonous, it could potentially give someone pains in their stomach if large quantities are ingested.

To store oobleck let it dry out in a bin open to the air, then refresh it with water when ready to use again. I tried storing it in an airtight container and after few days it spoiled.

Oobleck With Baking Soda

of baking powder to the water. Usually, this chemical is easily available. Nevertheless, if you can‘t get it, make it yourself by mixing one part of baking soda with two parts of cream of tartar. Stir for a maximum of 45 seconds.

Add ¼ cup of dry cornstarch to the bowl. Add about 1/8 cup (2 tablespoons, or 30 cm³) of water to the corn starch and stir slowly. Add water slowly to the mixture, with stirring, until all of the powder is wet. Continue to add water until the cornstarch acts like a liquid when you stir it slowly.

Put one tablespoon of school glue in one of the plastic cups. Then put one tablespoon of water in the same cup. Mix them together very well. If you like, now is the time to add food coloring.

Making Oobleck with Baby Powder

We used our standard 2 cups of baby powder and 1 cup of water and it turned into a perfect non-Newtonian Fluid. It had all the normal properties of our regular oobleck and behaved exactly like our regular cornstarch recipe.

Powders will typically behave hydrophobic, meaning that they do not readily mix into water. This causes the clumping mentioned in another answer and more commonly is seen in lumpy gravy and clumps of dry drink mix in the bottom of your glass.

The baby powder will help dry out pimples, and prevent your pores from becoming clogged with oil.

While baby powder can help reduce pimples without clogging pores, it is important you use it with caution when applying it near your face and lungs. Talcum powder is potentially harmful if inhaled, resulting in respiratory problems and some links to cancer, found in preliminary studies with lab rats.

The chemical ingredients in talcum powder, like silicates talc is not only a potent carcinogen, it also causes allergies and infection in lungs. Talc absorbs moisture and so we use talcum powder to avoid perspiration. But this causes much damage to our skin.
