We arrived early and made the 0.08% surfactant solution in Hasbrouck, then returned to Conte to prepare more films. I did not prepare films as I had acquired two sets of data on Friday for this concentration of surfactant. Dave and Efren met with success this morning and were able to acquire some data. After lunch, we downloaded the data onto our flashdrives then returned to Conte to use Image J and Excel (which Efren formatted with the appropriate formulas) to begin data analysis. We decided that we will float the films on pure water, then add the surfactant to prepare the 0.12% surfactant solution tomorrow, since we are already having trouble floating the fims with this lesser surfactant concentration.
