Ooblek is a Non-Newtonian fluid made with corn starch and water. A Non-Newtonian fluid is a fluid that doesn't follow Isaac Newtons laws of physics. This means that it isn't a solid, or a liquid, it is both.

       When not in motion, the Ooblek is a liquid. It flows, it fills its container, and you can pour it. But, when you apply pressure, this simple mixture turns into a solid.

       This happens because the long, straw-like particles of the corn starch latch together. Because of this reaction, the object applying pressure won't be able to pass through it. Just be careful, you might hurt your hand if you punch it too hard. You also add food coloring so it isn't just plain white.

       It is a very easy home expirament. For every 1 cup of corn starch you use, add 1/2 cups of water. You can add more water if you want it thinner, or more corn starch if you want it thicker. You can stir it with your hands or with a stick, or something. It might be a bit hard because of the reaction that I told you about earlier. Now, this might make a bit of a mess, so try to wear some old clothes that your not afraid of getting dirty. After that, just have fun! It might dry out after a while, so just add a bit more water.
