How to make Oobleck (Goop) | Easy 2 Ingredient Recipe DIY 

Here’s a fun poem I added to my IG page that I’ll also share here: 

Goop. 

Goop. 

It can’t be held for too long. 

It’s both a solid and a liquid state, 

And never both or you made it wrong. 

You can change its color by adding some dye, 

Intertwine it and mold it and create something epic and really – fly. 

Who am I? 

I love poetry. 

So, here is GOOP! 

We. Love. Goop. 

Aka.. Oobleck. 

Oh yes! Fun and easy experiments with cornstarch and water. 

Whenever we make this play goo, we all get so excited! 

This play stuff is amazing and I’ll be sharing how easy this 2 ingredient goop recipe is to make below!

Can you make oobleck with flour and water? 

We have tried this flour recipe oobleck method and I believe it did not work as the flour is not as fine and doesn’t contain the special ingredient – corn flour. 

I have read however that arrowroot powder will work as an alternative!

We have also attempted a cornstarch stress ball (oobleck style) that was just made by inserting the oobleck into a balloon. 

Then, tying the balloon up and squishing it for a fun and therapeutic stress ball.
