This oobleck recipe is very easy to set up and so much fun! 

We’ve made oobleck before but I don’t think we have themed it for a certain season before. 

This time around we made it orange and added in some fun Halloween themed props for a fun kids activity! 

Let’s get into it, shall we?

How do you make easy oobleck? 

Easy peasy! 

Oobleck is just a simple formula of 2 parts cornstarch to 1 part water. 

That’s it! 

Easy, right? 

We added in a third ingredient – food coloring. 

This was to make the oobleck orange! 

I added the food coloring into the mix but it would be much easier to add into the water, mix the water and pour it into the cornstarch! 

Here are the steps I took to put this simple and easy oobleck recipe together: 

• Insert 2 parts cornstarch into a bowl. 

• Then, add 1 part water mixed with a drop or two of food coloring into that same bowl. 

• Mix, mix and mix some more. 

• If you need to use your hands to mix, do that. 

• Then, you’ve created oobleck aka goop! 

• Easy peasy, right? 

I then added in a fun little set of recycled plastic cups and turned them into little ghosts for some fun props for the goop! 

My girls loved it! 

You’ll get this liquid/not liquid concoction and it is so much fun to play around with. 

Not only do my kids have fun playing around with oobleck, I do too! 😀

What is a good substitute for cornstarch to make Oobleck? 

A good substitute for oobleck would be two different powders..

They are arrowroot powder and tapioca powder! 

These two are so finely milled and will work as a wonderful substitute to oobleck aka goop! 

Can you use flour to make oobleck? 

Unfortunately it will not have the same consistency and using flour will not make oobleck. 

It will make a sort of paste like substance. 

Trust me, I have tried this before! 😀

Great alternatives to cornstarch are arrow root powder and tapioca powder due to their finely milled consistency.
