Running across a non-Newtonian fluid (oobleck) pool

This commercial features a 2,100 gallon pool of the cornstarch and water mixture known as oobleck, one of our favorite non-newtonian fluids. It was filmed in Kuala Lumpur by KIX for a Malaysian bank.

Make your own oobleck! 1 cup water, 1 to 2 cups cornstarch, and a bit of food coloring (optional). Read more at Scientific American or Wired, which explains:

British polymath and Enlightenment hero Isaac Newton studied lots of things: optics, gravity, waves, mathematics, astronomy, history, religion and alchemy and so on. Then in his spare time, he investigated how liquids flow and thus got a whole branch of fluid dynamics named for him. Newton observed how common liquids, such as water, flow the same regardless of how much stress you subject them to. Push a stirring stick into a cup of water and swish it around. The water’s viscosity – how smooth or sticky its consistency is – stays the same.

Pretty simple, yeah? Many liquids that we interact with on a regular basis work this way: things like water, milk, oil, or juice. But there are also a lot of common fluids that don’t. These are non-Newtonian fluids; substances whose viscosity changes based on how much pressure you apply to them.
