When was oobleck discovered?
The origin of the word is from a Dr. Seuss book named, "Bartholomew and the Oobleck. It is a non-Newtonian substance made of cornstarch and water that acts like a solid when force is applied.

When does oobleck act like a solid?
Oobleck is a non-Newtonian fluid providing a realization of a shear-thickening fluid.Non-newtonian means that at a state of rest, it acts like a liquid, but when outside force is exerted upon it, it acts like a solid.A good oobleck example is cornstarch with water, a common thickening agent used in cooking. It is also a very good example of a shear thickening system. When a force is applied to a 1:2.5 mixture of water and cornstarch, the cornstarch acts as a solid and resists the force.There is a nice explicative video on You tube in 'Related links' clickable just below this answer.

Does a penny sink in corn syrup?
A penny will rest on the surface of the cornstarch and water mixture only briefly before beginning to sink. Cornstarch and water, when mixed together, act as a non-newtonian fluid which acts as a solid when a sharp or sudden force acts. When a steady force acts, the material acts as a liquid and will flow or allow objects to sink through.
Is cornstarch a pure substance?
The mixture is Non - Newtonian liquid which means that it is a liquid unless a force is applied to it and then it has the properties of a solid. Sky 1 showed the properties of this well on Brainiac Science Abuse, where presenter ; John Tickle demonstrated walking on a pool of custard. Which is very similar to the mixture of Corn Starch and Water.
What is the effect on cornstarch and water?
Well, If you ever mix them together, stick your hand in to it and it will feel like mud in water. Then if you punch it, it will feel solid, but it won't hurt.
