10th Blog

       Today, we continued what we were doing yesterday. We took our bottles and flipped them upside down on top of a bucket. Then, we unscrewed the lids and got out all the glycerine and animal fat. Once we got all the useless things out of the bottle, few students helped pour the usuable oil into beakers. Ater that, we washed all our bottles with water and left our bottles open to let the water evaporate. Finally, we took off our aprons, goggles, and gloves. We worked on our lab report and looked up physical property tests for the rest of the class period.
