The Fluid on Which You Can Walk (12 pics + 1 video)

The most common of a non-Newtonian fluid is a suspension of starch (e.g. cornflour) in water. The sudden application of force — for example by stabbing the surface with a finger, or rapidly inverting the container holding it — leads to the fluid behaving like a solid rather than a liquid. This is the "shear thickening" property of this non-Newtonian fluid. More gentle treatment, such as slowly inserting a spoon, will leave it in its liquid state. Trying to jerk the spoon back out again, however, will trigger the return of the temporary solid state. A person moving quickly and applying sufficient force with their feet can literally walk across such a liquid. [Wikipedia]
That is what you will see in the video below. It really looks great, so don’t miss it!

Here is how to make it for yourself. Mix equal amounts of starch and water, perhaps a little less water, then stir.

Pour some the white liquid on your palm.

Roll the liquid into a little ball by quickly rubbing your hands together.

Slowly put your finger in a bowl of the liquid.

Sharply hit the liquid with another finger: The liquid will feel elastic, and your finger will stay clean.

Slowly place your thumb and index finger into the liquid.

Quickly squeeze your fingers and you will see a hard lump forming between them. It is not starch that causes it to harden; it is a non-Newtonian fluid that is showing its properties.

Try to dip all your fingers into the fluid and pull them out quickly.

Pour the starch from one bowl into the other. As you lift it higher you will see that the liquid flows from above, and becomes harder below.

In order to make the liquid remain hard you must continuously influence it by kneading.

Here is a marble made from the liquid.

However, as soon as you stop kneading it, the non-Newtonian marble once again becomes liquid and flows down through your fingers.
