0
00:00:00,000 --> 00:00:07,000
Okay, this is a bulb holder and in the bulb holder we have a nut that you can screw in

1
00:00:09,000 --> 00:00:16,000
or an screw, okay? As you can see we are going to collocate the bulb holder here and in order

2
00:00:16,000 --> 00:00:22,000
to do it we are going to make two holes and we are going to collocate the fasteners. So the first

3
00:00:22,000 --> 00:00:29,000
thing that we are going to do is to take a wire and we are going to strip the wire. In this part

4
00:00:29,000 --> 00:00:43,000
we have done it and now we are going to do it in the other one. I know that you have a

5
00:00:43,000 --> 00:00:51,000
pair of scissors, okay? So use your scissors. Okay, as always you have to roll it.

6
00:00:51,000 --> 00:01:06,000
Okay, now we are going to take the nut, we are going to open it or unscrew it

7
00:01:08,000 --> 00:01:17,000
and we are going to try to roll the wire around, we are going to try it, around the nut.

8
00:01:17,000 --> 00:01:22,000
Let's see if I can do it.

9
00:01:28,000 --> 00:01:32,000
It is difficult, eh? So be patient, you are not in a hurry.

10
00:01:34,000 --> 00:01:37,000
Okay, once that you have it more or less, okay,

11
00:01:41,000 --> 00:01:43,000
now you're gonna screw it.

12
00:01:48,000 --> 00:02:04,000
Okay, so more or less we have it, I think.

13
00:02:05,000 --> 00:02:14,000
Once that you have rolled the wire in the nut, you are gonna put the bulb holder

14
00:02:16,000 --> 00:02:18,000
on the cardboard and you are gonna make

15
00:02:21,000 --> 00:02:29,000
two marks in order to be sure that the measure that you're gonna take is correct. Now,

16
00:02:29,000 --> 00:02:47,000
you are gonna take one fastener and you're gonna make the hole, okay?

17
00:02:59,000 --> 00:03:03,000
So,

18
00:03:20,000 --> 00:03:26,000
and now we are gonna make another hole in the middle because we have to take the wire that

19
00:03:26,000 --> 00:03:36,000
is rolled in the bulb holder and pass it through it, okay? As you can see.

20
00:03:36,000 --> 00:03:54,000
Okay, now we take two fasteners, we co-locate it

21
00:03:54,000 --> 00:04:11,000
and we are gonna open them.

22
00:04:11,000 --> 00:04:25,000
Ta-da! Okay, now we are gonna continue with the battery, okay? This is the battery and in

23
00:04:25,000 --> 00:04:30,000
the battery we have two poles, the positive and the negative, okay? So, what we are gonna do is to

24
00:04:32,000 --> 00:04:39,000
flip over the cardboard and then we are gonna stick the battery here, okay? I'm gonna take

25
00:04:39,000 --> 00:04:51,000
a little of tape in order to stick it. So, it is going to look like this one, okay? So, first the

26
00:04:51,000 --> 00:05:01,000
tape.

27
00:05:01,000 --> 00:05:06,000
Okay,

28
00:05:21,000 --> 00:05:22,000
now we are gonna take the wire

29
00:05:22,000 --> 00:05:27,000
and we are gonna take the positive or the negative,

30
00:05:28,000 --> 00:05:31,000
the whatever, okay? The positive for the negative pole

31
00:05:39,000 --> 00:05:47,000
and you're gonna roll the wire on one side. As you can see, this is this one is the positive

32
00:05:47,000 --> 00:05:53,000
and the other one is the negative because here you have a plus and in the other you have a minus,

33
00:05:53,000 --> 00:06:01,000
okay? And like this. Now, let's continue with the following step. The following step is to take

34
00:06:01,000 --> 00:06:19,000
another wire, okay? And we are gonna strip the wire again.

35
00:06:32,000 --> 00:06:35,000
You have the scissors so you use the scissors, okay?

36
00:06:39,000 --> 00:06:45,000
Can we sit down or what?

37
00:06:51,000 --> 00:06:56,000
And then you take the final of the wire, okay? The one that you have stripped and you roll it

38
00:06:57,000 --> 00:07:01,000
on the other pole, okay? In this case, the positive but it doesn't matter if you put the

39
00:07:01,000 --> 00:07:09,000
other one in the positive and this one in the negative, okay? And it looks like this, okay?

40
00:07:09,000 --> 00:07:19,000
Now, we are gonna make a hole just to, one moment, to put the wire through the cardboard, okay?

41
00:07:19,000 --> 00:07:24,000
To pass the wire through the cardboard. So, we cannot use it like this but like this, okay?

42
00:07:24,000 --> 00:07:43,000
You can use the pencil to make the hole. It is easier but be careful, okay?

43
00:07:43,000 --> 00:07:57,000
Okay, super simple craft. Okay, now we are gonna take the other wire and we are gonna

44
00:07:57,000 --> 00:08:02,000
repeat the same action. We are gonna, if you can put the wire here, thank you,

45
00:08:02,000 --> 00:08:08,000
we are gonna strip the wire.

46
00:08:17,000 --> 00:08:22,000
And then remember that you have to roll the wire, okay?

47
00:08:23,000 --> 00:08:28,000
Okay, right. Now, we are gonna roll this wire into one of the fasteners.

48
00:08:36,000 --> 00:08:44,000
Ah, but in this size, no? Ah, okay, okay. Now, I understand.

49
00:08:45,000 --> 00:08:47,000
Okay, like this.

50
00:08:53,000 --> 00:08:55,000
Darling.

51
00:09:01,000 --> 00:09:03,000
Okay, perfect.

52
00:09:05,000 --> 00:09:07,000
Now, we are gonna put the wire here.

53
00:09:07,000 --> 00:09:19,000
Okay, perfect. Okay, now you have the both streams, okay? Or the both sides.

54
00:09:19,000 --> 00:09:25,000
And we are gonna continue. Now, we can say that it is complete but we are gonna try.

55
00:09:25,000 --> 00:09:33,000
Let's see, for example, let's picture a river. Ah, it is the other one.

56
00:09:33,000 --> 00:09:39,000
As you can see, when a river doesn't fit, the bulb doesn't light, okay?

57
00:09:39,000 --> 00:09:47,000
So, it switches on when it is the correct river, it doesn't switch off on when it is not the river.

58
00:09:47,000 --> 00:09:51,000
Okay, another one, for example, the Tajo.

59
00:09:55,000 --> 00:10:01,000
Okay, so you can try all the rivers to see if they are correct or not.
