Working with Corn

   Science class in ISB is always fun but this time it was awesome. The class was working with corn but not as a solid, it was powder. First, we filled a cup with water and then put some of the corn powder in a bucket and mixed it with water. As I was mixing it, I noticed it was like clay and hard. When it mixed just enough, I tried to pick it up but it didn't work, it became a liquid. I discussed that with my mate and our teacher, she said that this is one of the rare materials that is a solid and a liquid depending of what the pressure is like. So now that we succeeded in the task, we started experimenting and we put some more powder and more water, eventually we put a bit to much water and then it was mostly liquid.Working with this material, was a new experience for me because I never knew that something can be a liquid just as much as a solid. When we finished the experiment, we had to clean up. I took some of the left overs with me and this is how it looks like:




It is in a bag so it wont leak out. The color is the same as when we made it,white. The smell of the corn powder is not the best smell I have ever smelled, it smells like old powder or old cheese. If I touch it, there is a bit of liquid but some of it has became solid. During the next days, I will try to freeze it and will see what happens.
