Slow Motion Color Mixing Oobleck

The Hows and Whys Oobleck is a non-Newtonian fluid and one of the coolest substances around. Non-Newtonian fluids behave very differently than normal fluids in that they harden when pressure is applied to them and liquify when pressure is released. For example, when you roll the oobleck into a ball you apply pressure to it and it holds its shape of a ball. Then, when you set the ball in the palm of your hand, the oobleck turns back into a liquid and becomes a puddle of oobleck again. 1 cup cornstarch 1/2 cup water Bowl Spoon Tray Food coloring (at least 2 colors) Materials Needed Mix the cornstarch and water in a bowl and stir slowly until evenly mixed. Pour the mixture into a shallow tray. Add a few drops of food coloring to the mixture. Use at least 2 different colors.
