When Hank said how the cilia on the Gastrotrich's head were sensitive to the motion of the slide, I suddenly remembered that the camera was not panning over the environment, but that the environment was moving according to the slide. It really reminds you how perspective changes everything.

@@shashwatchamoli7221 When you use a microscope you have to put the microorganisms or cells on a thing called a 'slide' and that slide gets put on the stage of the microscope. The lens is what you look through but you don't move the lens to look all over the slide, you move the stage or the slide. Check out this crazy lady kzfaq.info/get/bejne/hdmao5aInMnLhGg.html

@@shashwatchamoli7221 sorry, I mean to reply yesterday but I guess I forgot. Yea, you're right moving the slide would do that but at the same time we're talking microns of motion so the liquid they're in shouldn't move very much. I guess that's why those hairy grandmas can sense this motion. I think that if they managed to move the lens instead that the microorganism wouldn't be able to feel the motion.

Speaking of the music, if you're into anime, the music has similar vibe or effect of those used in Mushishi. This channel actually reminds me of that anime. In Mushishi they explore the world of usually unseen "things" that affects the human world. And those things looks like these microscopic life. Its kinda similar how Greek mythologies try to explain everyday things using anthropomorphic gods but in Mushishi the things that causes maladies and stuff are these microbe-like things that are usually invisible to normal human. To anyone interested, it's a relaxing anime that covers mature and a bit of dark content.
