Oobleck Day at C.C. of Hoover was fantabulous! So. Much. Fun. Nikki, Eric, my parents, and myself put in a lot of hard work to make this our most spectacular science experiment ever. It took 150 pounds of cornstarch and over 15 gallons of water to make our non-Newtonian play day a huge success! Everyone seemed to have a super time and it will be a day we will never forget.
All fluids have a property known as viscosity that describes how the fluid flows – commonly thought of as how thick or thin a fluid is. When a fluid’s viscosity is constant it is referred to as a Newtonian fluid. Oobleck is an example of a non-Newtonian fluid whose viscosity is not constant, it changes depending on the stress or forces applied to it. If you poke it with your finger and apply a large force, it becomes very viscous and stays in place. If you gently pour it, applying little force, it will flow like water.
