00:00:02
we will look at a drop of water from a swamp
00:00:04
under a microscope,
00:00:05
I hope it will be interesting, let's go since
00:00:14
I live in a big city, I had to
00:00:16
go out of town to film a
00:00:18
new episode for you there,
00:00:19
initially I planned to catch different
00:00:21
types of insects and show they are under a
00:00:23
microscope for you, but I was very lucky, I
00:00:26
accidentally found a swamp and decided to take a
00:00:29
water sample from this swamp, and that’s how
00:00:31
this idea appeared, because in previous
00:00:34
issues I already showed you water from a
00:00:36
city river, also from a large
00:00:38
city lake,
00:00:39
and now the time has come to show water from
00:00:41
swamps and how good it is that I
00:00:44
had containers on hand for taking a water sample.
00:00:47
For those who are watching this video for the first time,
00:00:48
we will examine water under a
00:00:51
Leeuwenhoek 870 t microscope.
00:00:53
Well, if you haven’t seen previous episodes
00:00:56
about the microscope, then you should definitely
00:00:58
watch them, but now we We’ll be able to
00:01:00
compare water from a river to a swamp from a lake and
00:01:03
see what organisms live there,
00:01:05
look at it under a microscope, we’ll
00:01:07
only have one drop, but
00:01:10
I’ll repeat this procedure several times. By the way,
00:01:12
you know where you can find cool things with
00:01:14
unique prints, of course, on the
00:01:17
vsemayki website. ru a
00:01:18
huge selection of clothing, accessories with
00:01:20
original designs, 3D T-shirts,
00:01:22
sweatshirts and sweatshirts, backpacks, blankets with
00:01:24
bright prints, and you can also
00:01:27
edit a ready-made layout to your taste. a
00:01:36
magic button appeared and even if you have a
00:01:38
low-resolution picture, you
00:01:40
can always make your own cool design,
00:01:42
follow the link in the description,
00:01:44
order the promotional code we are from 51 in cotton wool and
00:01:46
get a full ten percent discount, but that’s
00:01:49
exactly what I saw in a drop of
00:01:51
water from this swamp at the moment this is the
00:01:53
very minimum magnification;
00:01:57
at medium magnification,
00:02:00
some microorganisms are already noticeable, but to
00:02:02
see more we will need a dark
00:02:05
field; this is a type of optical microscopy in
00:02:08
which the contrast of the image increases
00:02:10
by registering only the light
00:02:11
scattered by the sample being studied; in other
00:02:14
words, all living organisms will be visible
00:02:16
against a dark background
00:02:17
and at the same time, they will also be illuminated with
00:02:19
additional light; for this method, a
00:02:22
special dark-field condenser is required,
00:02:24
but the price for them is from $100 and
00:02:27
above, and therefore I was forced to come up with
00:02:29
my own version,
00:02:30
and if you are interested, then in the
00:02:32
next video I will definitely show how
00:02:35
I achieve this effect
00:02:36
using the dark field method, we would
00:02:38
now see what color this
00:02:41
microorganism has, after all, examine organisms in a
00:02:43
light field, some of them are not
00:02:45
visible at all, they are visible, but for example, in this
00:02:48
case, the abdomen of this microorganism is
00:02:50
dark, but if we direct the lighting in a
00:02:53
completely different way, we will be able to
00:02:54
examine it in detail the abdomen of this
00:02:56
organism and in general, thanks to the
00:02:58
dark field method, you can see something that cannot be
00:03:01
seen in a light field, so today,
00:03:03
thanks to the dark field method, we
00:03:06
will see you in a drop of water from a swamp to the
00:03:08
smallest detail,
00:03:09
but now I will try to comment a lot less
00:03:11
so that you can
00:03:13
enjoy this amazing a micro
00:03:14
world that somehow reminds me of
00:03:17
space
00:03:22
[music]
00:03:40
and
00:04:24
[music]
00:04:54
[music]
00:05:09
well, now everything can be compared that in a
00:05:12
bright field everything looks completely
00:05:13
different
00:05:15
[music]
00:05:22
in previous videos we have already met the
00:05:25
hydra but have never seen it in a dark
00:05:27
field
00:05:30
[music]
00:05:36
[music]
00:05:56
[music]
00:06:08
[music]
00:06:13
[music]
00:06:30
and this is what an ordinary daphnia looks like,
00:06:33
which also fell into this drop of water and
00:06:35
thanks to the dark field you and I can
00:06:37
study its structure in detail
00:06:42
[music]
00:06:54
[applause]
00:06:55
[ music]
00:07:01
[laughter]
00:07:03
[music]
00:07:07
by the way, pay attention to another
00:07:10
microorganism that has saddled this
00:07:12
organism; its mouth opens like that of
00:07:14
some alien creature
00:07:17
[music]
00:07:33
[music]
00:07:37
but this moment is not exactly
00:07:39
reminiscent of space
00:07:46
[ music]
00:07:51
and
00:07:59
[music]
00:08:38
and
00:08:39
well
00:09:07
[music]
00:09:31
by the way, pay attention to how
00:09:34
synchronous microorganisms sometimes are in movement
00:09:37
[music]
00:10:21
and
00:10:27
since I’m as new to the study of the microworld
00:10:30
as many of you, I tried
00:10:32
not to comment on this video because I’m
00:10:35
not I know what these organisms are called,
00:10:37
but I tried to show you the most
00:10:40
interesting thing, what is in a drop of water
00:10:42
from a swamp, if you liked this
00:10:44
episode, be sure to like it,
00:10:46
also suggest in the comments what else
00:10:48
you would like to examine under
00:10:50
a microscope, but if you want to see the
00:10:52
dirtiest city better under a
00:10:54
microscope, write in the comments the words
00:10:56
I want, but that’s all for now, bye everyone
