I picked up one of the small packets of iodized salt from Wilbur Dining hall on campus. I remember learning a bit about the properties of salt and its chemical structure in previous science classes, so I was interested in taking a look under the microscope! Preparing the sample was a bit tricky because the granules of salt from the dining hall are so small. In the end, I was able to make it work with the Foldscope by pouring some salt on a glass slide, adding droplets of water, and then securing the slide with a coverslip and tape. I had to quickly take a photo because the water often poured out from under the coverslip and took a lot of the salt with it. In the end, I think I was able to capture a pretty good photo of salt up close. I like how you are able to make out some of the crystal-like structures that form the salt granule.
