How do you make oobleck with flour?

You can't make oobleck with just flour! Oobleck is a non-Newtonian fluid that exhibits both liquid and solid properties, and its unique behavior comes from the combination of cornstarch and water.

Here's how to make oobleck:

Ingredients:

* 1 cup cornstarch

* 1/2 cup water

Instructions:

1. Slowly add water: Pour the cornstarch into a bowl. Gradually add the water, stirring constantly with a spoon or your fingers.

2. Consistency: The mixture should be thick enough to hold its shape when you squeeze it in your hand, but runny enough to pour. If it's too thick, add a bit more water. If it's too thin, add more cornstarch.

3. Play! Now you can experiment with your oobleck. It will feel solid when you squeeze it but will flow like a liquid if you let go.

Tips:

* Food coloring: Add a few drops of food coloring to your oobleck for a more vibrant look.

* Experiment with ratios: You can experiment with different ratios of cornstarch and water to see how it changes the oobleck's properties.

* Storage: Store your oobleck in an airtight container in the refrigerator for up to a week.

Why flour won't work:

Flour is primarily made of starch, but it also contains gluten. Gluten forms long chains that make dough elastic and sticky. Cornstarch, on the other hand, lacks gluten and has a much smaller, more compact starch structure. This structure allows cornstarch to form temporary bonds with water when pressure is applied, resulting in the unique properties of oobleck.
