This experiment was named after the book Bartholomew and the Oobleck by Dr. Suess because of how the experiment looks like (and is similar to) the Oobleck.
Oobleck is a type of non-Newtonian fluid called a dilatant. Its viscosity changes according to the condition to which it is exposed.
For this experiment, you will need three ingredients:
1 Cup of water
1 ½ - 2 Corn starch
Few drops of food coloring (if desired)
The original instructions say to mix the water and corn starch first, then add the food coloring. Some of the comments said to make mixing easier, add the food coloring to the water, which is what we did.
It was easier to mix this way, as we found out later on by adding more color to them.
It says 1 ½ to 2 cups, in case you need more, but to start with 1 ½ cup first. We only needed 1 ½ cup for the one with pink food color, but needed about 1 ¾ cup for the one with purple food color.
Then mix the water and cornstarch; you can use a spoon or your hands. Mix until well blended.
Lastly, have fun with it!
