Oobleck

This week, 4th graders are investigating whether oobleck (the combination of 1 1/2 cups cornstarch and 1 cup water) has the properties of a liquid or a solid.  Ask your 4th grader to tell you about the 9 tests they conducted with the oobleck. 

Take a look at this video of a person running on oobleck (in slow motion).  What do you think...liquid or solid?
