Update: Week 9

During Week 9, we took a closer look at the videos that were took the week prior to help further analyze our results. We also began to make the revisions to our rough draft of the final report. The group worked to complete final presentation slides need to start editing the videos.
To start we analyzed the two videos of the group member dropping the ice and then the prykete, we recorded our collective thoughts to come to an overall result. There was a distinct difference between the ice and sample 1 of the pykrete during the moment of impact with the ground. When the ice hit the ground it looked almost as if glass had shattered, where as the point of impact when the pykrete (sample 1) hit the ground it broke into 7 large chunks. This showed that when dropped from the same height that pykrete can withstand a greater impact when being compared to ice.

Figure 1 - Image of Sample 1 after being dropped from 3.5 feet. You can see that the paper towels kept the Pykrete from breaking into a large number of pieces. 

 Figure 2  - Difference between sample 1 and the ice. Notice the difference in the amount of pieces that resulted from the drop of the two blocks.

Figure 3 - In sample 2 all of the sawdust sunk to the bottom of the composite. Because of this the group believes that that if the sample had been stirred more during freezing the sample would have more resistant to fracturing compared to sample 1 and the control. 

Goals to work towards:

• Finish editing videos
• Finish up presentation
• Run through final presentation couple more times
• Make sure group members understand their talking points during the presentation
