What is Oobleck?
Oobleck is a non-Newtonian fluid; it has properties of both liquids and solids. Its pressure dependent – You can slowly dip your hand into it like a liquid, but if you squeeze the oobleck or punch it, it will feel solid.
The name oobleck comes from the Dr. Seuss book, “Bartholomew and the Oobleck.” In the story, oobleck, a gooey green substance, fell from the sky and wreaked havoc in the kingdom.
Oobleck makes a great science project or simply have fun playing with it, like us. 😀

Miss A(3yrs) & Miss D(2yrs) had so much fun playing with it. I underestimated this activity – didn’t expect it to be this awesome. We all enjoyed it! (Even hubby!!). It was an amazing experience. My kids were playing with it for more than an hour. They did get themselves and the place messy but cleaning was easy – just clean using water 😀 Plus all those laughing is so much worth the mess.
You could also make huge quantities of oobleck – in kids water pool and enjoy it outdoors. If you make enough, you can even walk on it. Something i want to try in summer.
Here’s what we did with the Oobleck
- Grab a handful and squeeze it – it oozes through your fingers.
- Make a puddle and quickly drag your fingers through it. My LOs tried to cut it using playdough knife.
- Roll some oobleck into a ball. It becomes solid, but when you stop moving it, it will melt back into your hand.
