Spooky Oobleck!

My guys have been chomping at the bit to make a fall sensory project (see our favorites round up here) and I thought it would be fun to loop in a little science at the same time (it's on our Fall Bucket List after all!). So we decided to make a batch of spooky oobleck!



If you've ever made oobleck, you'll know this fabulously fun sensory mixture is a non-Newtonian substance -- it behaves like a solid or a liquid depending on how much pressure you apply. Our Spooky Oobleck is not only a great lesson in viscosity, but a fun way to have your kids make slimy monsters (that also happen to smell pretty great). It's also a perfect outdoor activity to get in before the fall chill really hits.

To make our Spooky Oobleck, you'll need:
- 2 cups cornstarch
- 1 1/2 - 2 cups water
- orange food coloring
- pumpkin pie spice
- googly eyes

Start by having your kiddos mix1 1/2 cups of water into the cornstarch. Depending on how well they measure and mix, you might need to add up to a 1/2 cup more of water. You want the mixture to pour easily, but feel solid when you exert pressure on it.

Add in a few drops of orange food coloring and mix it in well. Do the same with a few dashes of pumpkin pie spice and the googly eyes. Let the kids play with it by itself or add a few simple accessories for additional fun -- my little scientists like to scoop and pour it, making slimy monsters with their hands. Perfect seasonal science!
