 Video examining pond water searching for organisms around algae. One likely organism observed as it seems to be moving by its own power not that of the flow of the water. Sample obtained 4/11/2019 6pm from the Turtle Ponds at Caltech using a cup.


 Based on the reported magnification of 140X and a scale placed under the foldscope the organism seems to be somewhere in the range of ~300 um.

Figure 1 is a foldscope image of the stamen of a Hibiscus flower. Small pollen particles from the stamen are the most visible as small yellow balls with rough surfaces. A picture of the flower from which the sample was obtained is also included (figure 2). The sample was obtained outside of the south face of Page house on Caltech’s campus on May 9th, 2019 at 12:30 pm by removing the stamen and placing them on a glass slide with a coverslip.
