Fall is an excellent time of the year to put a little twist on classic science experiments like this spider oobleck! We have tried a few themed oobleck recipes this season including applesauce oobleck and pumpkin oobleck. How about a spider oobleck for Halloween? Fun science, fine motor, and sensory play in one easy activity!

WHAT IS OOBLECK?

Oobleck is usually 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.

How does oobleck work? 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 liquid, a substance that acts like both a liquid and a solid.

You can make tons of fun variations of oobleck. Check out these ideas below…

WHAT TO DO WITH YOUR SPIDER OOBLECK

My son played rescue the spiders for quite a while. He enjoyed poking at the oobleck, making paths in it and watching chunks melt back into the large mass.

Oobleck really is a cool and unique substance for kids to explore. Adding a pair of tweezers just enhances fine motor skills in a playful way. The oobleck provides a nice resistance for hand strengthening too while manipulating the tweezers!

This can get as messy as you like it! He preferred that I get messier. He enjoyed watching the oobleck pour out of the container, burying the spiders and rescuing them again and again.
