Mr. O shows his audience in this video how to make oobleck, a slime-like substance which has a variety of unique properties. For this project, you will need a mixing bowl, food coloring, corn starch, a measuring cup, and water. First, color the water with food coloring to a color which is much darker than the color you would like. You will need the correct ratio of water to cornstarch, in a 1 to 2 ratio. Add some water to the bowl and add the cornstarch, then add the rest of the water. Finally, you should use your hands in order to knead the cornstarch and the water together. The resulting oobleck is both a solid and a liquid, which stays as a liquid when moved slowly, but which seems like a solid when you hit it with force.
