Video recording of microscopic examination of puddle samples. In the samples, we observe mosquito larvae, algae, copepods, and annelids. The categories we have been using so far are no longer applicable in the case of organisms like algae. For a long time, they were considered spore-bearing plants, later they were classified into other groups of plants, fungi, and even animals. The organisms shown in the video are studied using various types of radiation. Also present is the flexible annelid, which plays an important role in soil and sediment enrichment as well as in the mineralization of organic substances. Unfortunately, our eyes are not innocent–the annelid dies under the influence of irritating light. The video is accompanied by metal objects. Their shapes are inspired by detritus seen under the microscope, which is a finely fragmented, dead organic matter–remnants of plants and animals.
