DIY sealed micro-ecosystem for microscope timelapse videos

This technique prevents evaporation and keeps microbial communities alive for weeks, allowing study of long term processes, egg development, algae growth, fission reproduction. Microbes featured in this video include rotifer, gastrotrich, haltotier, copepod, paramecium bursaria, uroleptus, coleps, euplotes. Adapted from David Walker's article in the Sept 2020 issue of Micscape http://www.microscopy-uk.org.uk/mag/a... My previous video on 3D techniques "DIY simple 3D microscopy filters, polarization or red/blue anaglyph"    • DIY simple 3D microscopy filters, polariza...   Also presented (and updated) in an article in Micscape: "3D viewing and recording with a non-stereo binocular microscope" http://www.microscopy-uk.org.uk/mag/z... Viewing 3D directly through the eyepieces with the polarizing technique gives a better experience than the red/blue glasses on the monitor, but is trickier to set up. I've only tried it on my AmScope T490 and iScope 1153EPC, both of which split the light to send the image to the binocular eyepieces and trinocular port simultaneously. This may affect the polarization differently from simple binocular microscopes or the trinoculars that let you select eyepieces alone, trinocular port alone or simultaneous. If anyone else tries it on other microscopes I would appreciate any comments on the results.
