	For Set 1, our purpose in using the petri dishes was to create a larger surface area for the hydrogels to form. After preparing our water/oil emulsion and placing in the freezer for ~10min, it was apparent that although there would be a greater separation between the gels that form, there would still be significant adhesion between them. Because of this, we decided to only to do one sample in the same way using mineral oil, just to see if there was any difference. For Set 3, we used safflower oil and flash froze our sample prior to placing in the freezer. This method was done on all three samples.
