MSED250: Oobleck and Glurch lab

01/24/2021:

To further expand my understanding on solutions and phase of change, my professor constructed a lab that allowed my partner Kayla and I to mix and create Oobleck and Glurch. During this lab we were provided with the following: 

Materials:

Glue

Borax 

Measuring tools 

Mixing tools 

Beakers and flasks 

Water 

Zip lock bags 

Corn starch 

In order to complete this lab we first started by creating the Oobleck. To do this we first measured out 3/4 cup of glue, and poured it into a beaker. Next we added 1 teaspoon of water and mixed the two together. Following this we then created the borax solution which consisted of 1 tablespoon of borax and about 1 cup of water. Once the borax had completely dissolved we added the solution to the glue and water mixture. In result we were left with a elastic like substance. The pictures below show the result of my partner and I making the Oobleck.  

Next we created the colloid solution glurch. First my partner and I poured about 1/2 cup of corn starch into a zip lock bag and slowly began to add water. As we added the water the cornstarch began to harden as we manipulated it. Once we achieved the desired texture we poured the solution onto the table and discovered that the solution was hardened whenever it made contact with a solid object. The pictures below document this experiment.
