=Oobleck...WHAT????=

Introduction
I always wondered how the Oobleck changed form from solid to Liquid or Vise Versa. After I researched about it I started think how are the other liquids (for example: Gravy) effected by corn starch.

Hypothesis
I think it will not matter because they all are liquids.

Materials

 * Corn Starch
 * Food Coloring
 * Vegetable Oil
 * Vinegar
 * Water
 * Rubber Gloves
 * Trash Bags
 * 1/2 cup
 * 1 cup

1. I got 1 1/2 cups of Corn Starch
2. I poured it in a bowl marked water 3. Then I got 1 cup of water and poured it in the bowl 4. Then I mixed them together 5. I got another bowl for the following 6. I poured 1 1/2 cups of Corn starch in the bowl 7. Then I got 1 cup of Vegetable Oil. 8. I poured it in the Bowl 9. Then I mixed it all together. 10. Then I got and another bowl 11. I got 1 1/2 cups of Corn Starch 12. I poured it in the bowl 13.I got 1 cup of Vinegar and poured it in the bowl. 14. I mixed them the ingredients together. 15. Once I finished Mixing these ingredients I brought out three people: Tristan Winans, Miss Fitz, and Morgan Standard, to tell me how the texture feels. 16. Once they had observed the Oil they informed me it did not have the same texture as the other two mixtures. 17. So I had to change the amount of Corn Starch in the Vegetable Oil. 18. Once I added the extra corn starch it still did not change the texture.

Results
The Vegetable Oil did not have the same texture as the regular Oobleck, but it was a lot more creamy of a texture. I had to change how much Corn starch I put in with the Oil but it still had the same creamy texture. The Vinegar did not have the same texture at the beginning of the experiment but after I let it sit for about 30 min. it started to thicken and turn into Oobleck.

Discussion and Conclusions
What caused the Oobleck to act like a solid or like a liquid? Pressure. When enough pressure was applied, the Oobleck acts like a solid. When little or no pressure is applied, it acts like a liquid. Why do you think Oobleck acts like this? What size are polymers in the world of atoms and molecules? Polymers are very long chains. How might that influence the behavior of Oobleck? When pressure is quickly or heavily applied the chains have less time to move and get tangled up. When little pressure is applied, the chains have time to slide past each other.
