Oobleck, or sensory goop, is super uncomplicated to make and there’s a surprising quantity of entertaining strategies you can find out from and play with it!

Updated May 2021

Oobleck is a fully mesmerizing material for little ones to touch and play with. Since it is just cornstarch and water (plus any colour you want to add), it is super uncomplicated and economical to make. It’s also taste secure and non toxic, producing it a wonderful sensory play material for babies and toddlers.

Sometimes it acts like a strong. Sometimes it acts like a liquid.

And, to add to the weirdness, oobleck acts differently from a standard liquid and differently from a standard strong.

How is that probable?

Oobleck is a non-Newtonian fluid, which means it is a stress-dependent substance.

If you boost the pressure on the oobleck, it increases the viscosity or thickness. But if you poke at it rapidly, it feels like a strong. And if you hold some in your hand, it will ooze out of your fingers like a liquid.

(Just for reference, other non-Newtonian fluids incorporate quicksand and Silly Putty).

Since our 1st batch of sensory goop, we’ve created oobleck several other occasions. Sometimes with toddler art groups, often on our personal, often at birthday parties. We’ve accomplished it inside and outdoors, in modest batches or significant, frequently playing with it making use of hands, tools, and even feet.

Here’s how to make oobleck (it is super uncomplicated!) as properly as some of the entertaining issues to do with it. If you like, get started by reading Bartholomew and the Oobleck by Dr. Seuss, the book that inspired this goop’s entertaining name.
