Is it a liquid? Is it a solid? Oobleck is a non-Newtonian fluid, meaning it acts as both a liquid and a solid. You can scoop it and roll it into a ball (a solid), and then it oozes out of your hand (like a liquid)! Available in a variety of colors.

This activity is toddler-safe and contains only non-toxic and washable materials.

Fun product and great seller

We had the oobleck sent to our Grandson’s house to be there for our visit. It was a great project for some Grandparent/Grandchild fun time!

Lots of fun

Bought this for my nephew's birthday. He just tried it today and had a lot of fun with it.

So Cool!!!!!!!

We broke this out on a Saturday afternoon and our kids couldn't get enough! So fun squeezing this goop through their hands (and if I'm being honest I joined in too). Adding a little water at a time to see how it would change the viscosity made for a great discovery/sensory activity. Just buy it - you won't regret it!

Fabulous slime

This slime is so much fun!! Adults love playing it with it as much as the kids! Great sensory feels!
