Making Oobleck (Fun Kitchen Science!)

Leave a comment

We’re in the midst of learning about states of matter in Kindergarten.  I can’t think of a more interesting matter experiment than this one – an old recipe from a Teaching Elementary Science class – concocting “Oobleck.” 

Oobleck is hard to classify – it’s a liquid, but much like a solid.  It gets drippy in your hands and then reverts back to a solid state.  I have always loved hearing students make observations about it. 

Beyond the cool problem solving factor, it’s just fun to play with.  It would be a great April Fool’s Day experiment or a good gross one for boys of any age.  Plus, it’s great for fine motor development.  Because Selah loves to immerse her hands in paint, mud, dough, whatever – this stuff was an absolute hit!  Let me know if you try it!

Oobleck Recipe

1 cup of cornstarch
