Traditional oobleck is a mixture of cornstarch and water. Roughly a 2:1 ratio but you can tinker with the ratio to find a desired consistency that still maintains the properties of oobleck.

What’s the science of oobleck? Well, it’s a solid. No wait it’s a liquid! Wait again, it’s both! Very fascinating to be exact. Pick up solid chunks,  pack it into a ball and watch it ooze into a liquid. This is called a non-Newtonian fluid, a substance that acts like both a liquid and a solid. Slime is another great example of a non-Newtonian fluid!

For our winter oobleck version below we added some evergreen branches, pine cones and cranberries.
