Liquid or Solid?


Today in class we did a lab called Wonderful, Glorious Goop. In this lab we mixed together cornstarch, water and food coloring to get a certain mixture of purple goop. There were a lot of interesting things that happened in this experiment but three of them are:



  1. When you apply heat and pressure it is a solid

  2. When you open your fingers it seeps through like a liquid

  3. This substance is called an amorphous solid

I have found that this experiment is very popular and there are a lot of interesting fact on line about it. Two fact i found are:



  1. You can walk on this mixture if you keep moving fast enough

  2. If you add different amount of liquid of a different liquid you will get a substance that will work very differently

In my opinion think this lab was a fun way to learn about all the different substance between a solid and a liquid. This substance is called an amorphous solid. Because of this lab, I completely understand what this substance is. I love this lab and hope to do it again in the future.
