How to make Oobleck

  • by

Oobleck is a thick, gooey substance that you can make at home.

It’s a non-Newtonian fluid meaning it’s a liquid when being stirred but becomes solid when hitting a hard surface.

Scientists have found that Oobleck feels different to people due to the textures and sensations they feel as the oobleck dries.

To make oobleck, take a bowl or container and fill it with water. Add 1 cup of cornstarch and stir until combined.

If you’re feeling brave, throw in some food coloring for even more fun! Once the oobleck feels solid enough for your liking, transfer it into another container to finish creating your masterpiece! You can use stamps, cookie cutters, playdough tools and more to create a design.

Then have fun playing around with it! It is recommended that you do not touch oobleck with your hands because it slows down the germination process of plants.

If you’re wearing a white shirt while playing with oobleck, you will get messy! Oobleck is known to stain clothes, especially white ones.

This is not a toy; it can be dangerous if handled improperly. If your oobleck starts turning back into water, that means that there’s too much water in the mixture and you should add more cornstarch to thicken it up again.

Always keep young children away from oobleck and never allow them to handle it by themselves. Oobleck can be played with on a hard surface or outside so that if it does turn into water, it won’t ruin any furniture or flooring.

So this is how you can make Oobleck.
