HALLOWEEN OOBLECK

(Article from littlebinsforlittlehands.com)

Oobleck is a classic science activity that can be themed for a number of holidays or seasons! Of course it’s easy to turn into a Halloween science experiment with a few creepy crawly spiders and a favorite theme color!

You will need cornstarch, water, and food coloring. You want to start with a ratio of 2:1, cornstarch to water. I would start by adding food coloring to the water and then add more to the mixture of necessary.

TIP: If it’s too soupy, add cornstarch. If it’s too hard and dry, add water. Only add in small increments till you get the desired consistency.

Oobleck is a Non-newtonian fluid which means it is neither a liquid nor a solid. You should be able to pick up a chunk of oobleck and form it into a ball before it turns back to liquid and drops back down to the bowl.
