This image depicts water from a pond on Caltech campus viewed using a Foldscope. The sample was collected on 4/9/19 and the picture was taken at around 9:00 pm. The particles seen are likely bacterium (domain Bacteria), although they were observed not to be moving. If they are not bacterium, they could also be some microbial plants or debris. I am curious as to how I would take a clearer image using the Foldscope. Next time I will experiment with different viewing angles and magnification settings.
