Diatoms - glass cells, seen under the microscope.

Thank you!

Thank you for these videos. As I mentioned in the comment on the previous video, I don't currently have a microscope, so these videos are doing two things:
1/ Giving me a chance to see what I would see if I had a microscope
2/ Tempting me into saving money to get a microscope.

made of a dielectric, some are even toroidal or helical... if you want to learn about energy harvesting, study these little fellas...

From 1:19 in the top right is a long thin object with a spiral of green inside was that a microbe or plant?

[@microbesmatter999]

That's a plant - probably algae. I usually add a lot of it to my samples for extra oxygen.

[@Ashleygeneralstuff]

@microbesmatter999 I was intrigued because of the spiral.

[@Ashleygeneralstuff]

Sorry - one more question you put, say, 200qm - is that μm - in other words micrometres?

[@microbesmatter999]

Yes, that's correct
