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.
