Oobleck: The most fun sensory experience for any child!

This sensory science experiement is not only fun for children, but equally as fun for adults. And the best part? It washes away super easy with water. That all sounds like a big win for me!

Oobleck is a classic sensory/science play experience that has been around for years and years. I bet if you ask your parent, they will have memories of playing with it as children.

If you haven’t seen or tried Oobleck before, you are in for a real treat!

So what is Oobleck anyways?

Oobleck is a non-newtonian fluid. That means it acts like both liquid AND solid. It’s a liquid when you pour it, but a solid when you touch it (force on the oobleck causes it to act like a solid, such as poking or scooping it).

When you grab a handfull, it will start to ooze and slip between your fingers and off your hand.

I have to admit, I just recently came to find out that Oobleck is called…Oobleck. I have always called it “Corn Starch Magic”. I now know that they are the same thing! So whatever you call it, you’re going to have a blast!


Oobleck gets its name from a Dr. Seuss book called Bartholomew and the Oobleck!? In this book, a green substance, Oobleck, falls from the sky and causes chaos in the kingdom.


  1. Corn Starch
  2. Water
  3. Bowl or container
  4. Food colour (optional)


Start by placing corn starch in a bowl, then slowly add water.

Oobleck always turns out great if you use equal parts water and corn starch. However, I like to add the water slowly and have the littles mix as I pour the water. This way you can get it to a consistency that your littles enjoy!

You can add the food colour to the water before mixing with corn starch. You can also make the oobleck and then add colour afterwards. This way you can really see the colour mixing!

Try adding some toys to the Oobleck, or pouring it over a wire drying rack.

Whatever you do, you are guaranteed to have fun!
