Bartholomew and the Oobleck

There is a book by Dr. Seuss titled, "Bartholomew and the Oobleck".  I had never read the story, until I was going through Pinterest one day, and found a recipe for Oobleck.  So, out of curiosity, we got the book from the library, and read the story to my little babysitting buddies, ages 3 and 1.  I found it to be quite an interesting story. 

Afterwards, we made the oobleck.  I have to say that I absolutely love playing with this stuff as much as the 3 year old did!!  Here is how you make it. . . .
                         You will need:  2 cups cornstarch
                                                1 cup water
                                                 food coloring

Mix 2 cups of cornstarch and 1 cup water in a bowl. To color oobleck, add a few drops of food coloring to the water before adding to the cornstarch. Takes some effort to mix the water and cornstarch. Oobleck defies Newton’s third law of motion–for every action, there is an equal and opposite reaction. If you quickly smack oobleck with your hand it immediately turns into a solid, instead of splashing or moving. If you slowly move oobleck it reacts like a liquid.

Note:  Oobleck picks up bacteria from the air, and the starch makes a perfect food source, so the bacteria grows rapidly.  Within a couple of days, it will start emitting a foul smell, so you will need to discard it.
