1
00:00:09,740 --> 00:00:11,240
Hey, hello everyone.
2
00:00:12,140 --> 00:00:12,860
My name is Mr.
3
00:00:12,860 --> 00:00:13,229
Yaro!
4
00:00:14,300 --> 00:00:17,180
And today in this video, I
want to talk about chemistry.
5
00:00:17,450 --> 00:00:22,550
A little bit about chemistry and
especially about three states of matter.
6
00:00:23,210 --> 00:00:27,280
So as you know, the matter
around us have different states.
7
00:00:28,340 --> 00:00:31,335
It can be solid, liquid or gas.
8
00:00:31,875 --> 00:00:35,295
Also, we know that all
matter made of molecules.
9
00:00:36,105 --> 00:00:40,815
In gas condition, all molecules
placed really rare from each other.
10
00:00:41,864 --> 00:00:43,004
In the liquid condition
11
00:00:43,285 --> 00:00:46,245
the molecules placed
more closer to each other.
12
00:00:47,355 --> 00:00:52,144
But in solid condition they all together.
13
00:00:52,365 --> 00:00:53,855
Like close close to each other.
14
00:00:54,675 --> 00:00:59,145
Between molecules we can find a
special connection named Bonds.
15
00:01:00,025 --> 00:01:03,775
So more bonds - more connections,
more stronger material.
16
00:01:04,935 --> 00:01:07,905
And right now I want
to make one experiment.
17
00:01:08,235 --> 00:01:09,615
In this chemical experiment
18
00:01:10,054 --> 00:01:14,295
I well make more bonds
between molecules in liquid.
19
00:01:14,685 --> 00:01:16,545
And this liquid will become stronger.
20
00:01:17,025 --> 00:01:21,414
More bonds can make special
chemical named cross-linker.
21
00:01:23,130 --> 00:01:24,000
So let's start!
22
00:01:24,700 --> 00:01:28,860
For this experiment I need
50 milliliters of PVA.
23
00:01:50,730 --> 00:01:53,110
Next, I will add shaving foam.
24
00:01:53,340 --> 00:01:54,120
Just a little bit
25
00:02:00,740 --> 00:02:01,330
Toothpaste.
26
00:02:11,360 --> 00:02:14,780
And two food colors, blue
27
00:02:21,250 --> 00:02:22,050
and rose.
28
00:02:29,910 --> 00:02:31,520
Now I need to mix it well.
29
00:02:32,030 --> 00:02:32,120
Okay.
30
00:02:38,480 --> 00:02:38,870
Okay.
31
00:02:39,620 --> 00:02:41,840
And now it's time for final ingredient.
32
00:02:42,600 --> 00:02:45,215
I will add this cross linker.
33
00:02:45,525 --> 00:02:47,995
This is soduim borate.
34
00:02:48,575 --> 00:02:53,085
And sodium borate can create more
bonds between this molecules.
35
00:02:55,625 --> 00:03:00,995
I will add 2.5 milliliters
of this solution.
36
00:03:20,595 --> 00:03:21,565
Now it's time to mix.
37
00:03:23,345 --> 00:03:26,495
The time of reaction
approximately two to four minutes.
38
00:03:26,675 --> 00:03:28,595
And all the time I need to mix it well.
39
00:03:34,775 --> 00:03:36,815
Look at this sticky liquid.
40
00:03:37,615 --> 00:03:38,255
Eeeeeeee.
41
00:03:39,359 --> 00:03:40,380
So we call it slime.
42
00:03:41,010 --> 00:03:41,700
It's not liquid.
43
00:03:41,910 --> 00:03:42,900
It's not solid too.
44
00:03:43,230 --> 00:03:44,430
It's something in the middle.
45
00:03:47,480 --> 00:03:48,709
Well, slime can be different.
46
00:03:48,709 --> 00:03:50,519
Can be very gooey.
47
00:03:51,170 --> 00:03:53,610
Or very chunky - very solid.
48
00:03:53,920 --> 00:03:54,810
For example, this one.
49
00:03:58,370 --> 00:03:58,460
Look,.
50
00:03:59,820 --> 00:04:02,499
not so sticky, even can the jump.
51
00:04:08,265 --> 00:04:11,325
So I hope you can make slime
at home and have fun with it.
52
00:04:12,335 --> 00:04:13,055
See you next time.
53
00:04:13,265 --> 00:04:13,415
Bye.
54
00:04:13,415 --> 00:04:13,685
Bye.
