 This is an image of a sample of Caltech’s Turtle Pond water. The sample was obtained on April 8th, 2019 at 7:00 PM using a pipette. It was put on a slide and examined using a foldscope. The image was taken with an iPhone camera.


 From the image, it is clear that there are no organisms in the sample. The brown spots scattered throughout the image are likely just pond scum.
