How to make oobleck without cornstarch

A super simple and easy recipe that only requires baking soda & baking powder.

  • 4 tbsp of Baking Soda
  • 4 tbsp of Baking Powder
  • 1/2 Cup of Water

  • Add 4 tablespoon of baking powder to the water.
  • Stir for 45 seconds.
  • Add 4 tablespoon of baking soda.
  • Continue stirring for a good 1 to 2 minutes until you see a thick consistency.

2 – Potato Starch

Yes, you read that correctly! We can use potatoes to make oobleck. Well, potato starch that is!

Ingredients:

  • 2 cup of Potato Starch
  • 1 cup of Water

Instructions:

  • Mix the potato starch and water together in a bowl.
  • Stir until you get the consistency of oobleck.

3 – Tapioca/Arrowroot Powder

I honestly had no idea that tapioca powder/flour would behave the same way as cornstarch Who knew!

Ingredients:

  • 250g tapioca powder
  • 250ml of water (room temperature)

Instructions:

  • Empty the tapioca powder in a bowl.
  • Add the water at room temperature to the bowl.
  • Mix well.
  • If the consistency is too wet/liquid, add more powder a little at a time.

Can we use flour to make oobleck?

No, flour cannot be used to make oobleck. When you mix water & flour, you’d get a glue-type consistency which is unlike the consistency of oobleck.

Is oobleck edible?

If you child takes a bite you don’t have to worry too much. Oobleck is a taste-safe activity. I would advise against eating the oobleck in large amounts as it may cause digestive issues.

How long can oobleck be stored?

I do not recommend keeping the oobleck longer than 24 hours or it could become moldy. NOTE – Always dispose of your oobleck in your trash – NOT in your sink. 

Is oobleck safe for toddlers?

Oobleck is super safe for toddlers as it uses non-toxic food-grade ingredients. If they ever decided to explore with their mouth, it is very safe for them to do so. As said above, I would not recommend eating oobleck in large amounts as it may cause an upset stomach.
