00:00:00.000 --> 00:00:01.760
I'm with Colin Furze.

2
00:00:01.760 --> 00:00:02.540
That's me.

3
00:00:03.320 --> 00:00:06.540
Dangling upside down with magnetic shoes that he's made.

4
00:00:06.860 --> 00:00:08.360
Colin, do you want to explain how these work?

5
00:00:08.880 --> 00:00:10.360
Basically,

6
00:00:10.360 --> 00:00:12.140
we've got a microwave transformer,

7
00:00:12.140 --> 00:00:14.440
you cut it in half, take one of the coils out,

8
00:00:14.440 --> 00:00:17.020
and you end up with this, like a little E-shaped block,

9
00:00:17.020 --> 00:00:20.160
whack a car battery on it, and you've got a super strong electromagnet

10
00:00:20.160 --> 00:00:23.460
which if you then put in some shoes, you can make magnet shoes!

11
00:00:23.460 --> 00:00:25.080
Which are great aren't they Tom!
They are!

12
00:00:25.080 --> 00:00:27.160
Surprisingly physically demanding, this.

13
00:00:27.160 --> 00:00:29.620
Um, but let's talk about fail-safes.

14
00:00:29.620 --> 00:00:32.440
Because, well, these electromagnets can be used in a lot of things

15
00:00:32.440 --> 00:00:34.480
they're used in the doors in the office I work,

16
00:00:34.480 --> 00:00:36.800
and those doors are fail-SAFE.

17
00:00:36.800 --> 00:00:39.320
Fail-safe does not mean we have a backup,

18
00:00:39.320 --> 00:00:41.900
fail-safe means they fail, and it is safe.

19
00:00:41.900 --> 00:00:45.720
You see if the power fails, if there's an emergency, something like that,

20
00:00:45.720 --> 00:00:50.740
then everything's fine, the doors unlock automatically because there's no power, and everyone can get out.

21
00:00:51.540 --> 00:00:54.100
There is an opposite to fail-safe, which is fail-deadly,

22
00:00:54.100 --> 00:00:57.200
and you usually find that in things like nuclear submarines,

23
00:00:57.200 --> 00:01:01.060
who have orders to fire if everything falls to pieces.

24
00:01:01.620 --> 00:01:04.760
These shoes? Well they may not be fail-deadly, but they're certainly

25
00:01:04.760 --> 00:01:09.140
fail-unsafe, because if the electromagnets fail, or if the battery fails

26
00:01:09.140 --> 00:01:13.880
or if I, accidentally, push one of these shiny red buttons here,

27
00:01:13.880 --> 00:01:20.320
well, then I fall to the ground, neck first, swiftly followed by the incredibly heavy magnetic shoes

28
00:01:20.740 --> 00:01:23.440
which, will probably kick me in the face.

29
00:01:24.460 --> 00:01:27.540
So with all due respect to your invention Colin, which is marvelous,

30
00:01:28.280 --> 00:01:29.960
can I come down now?
Yep.

31
00:01:30.780 --> 00:01:32.460
You're looking as red as your t-shirt.

32
00:01:32.460 --> 00:01:35.280
Oh my God it takes so much out of you, this does!

33
00:01:35.280 --> 00:01:36.320
That's wonderful.
There you go.

34
00:01:36.320 --> 00:01:39.380
Colin's channel is on screen now, he has all sorts of wonderful things

35
00:01:39.380 --> 00:01:42.860
like a jet powered bicycle, and world-record attempts.

36
00:01:45.400 --> 00:01:47.200
Thank you very much!
It's all right.

37
00:01:47.820 --> 00:01:52.080
That, was take 4, and I am not doing that again.

38
00:01:57.900 --> 00:01:59.920
You really appreciate gravity now don't you?

39
00:01:59.920 --> 00:02:00.800
Thanks Colin.
