WEBVTT Kind: captions Language: en 1 00:00:00.000 --> 00:00:02.680 This is not going to be a normal video. 2 00:00:02.690 --> 00:00:05.900 We're sending garlic bread to the edge of space! 3 00:00:15.240 --> 00:00:17.900 Loads of people have launched loads of objects on balloons, 4 00:00:17.900 --> 00:00:19.200 usually as publicity stunts. 5 00:00:19.210 --> 00:00:21.750 But despite a lot of breathless press releases 6 00:00:21.750 --> 00:00:24.420 those objects haven't been launched into space. 7 00:00:24.420 --> 00:00:27.630 Most standards organisations agree that space officially starts 8 00:00:27.630 --> 00:00:32.110 at the completely arbitrary Kármán Line, 100 kilometres up. 9 00:00:32.110 --> 00:00:34.720 And balloons like that one only get about a third of the way there. 10 00:00:35.440 --> 00:00:38.510 And we're definitely not sending anything into orbit. 11 00:00:38.510 --> 00:00:42.020 Orbit requires tens of thousands of miles-an-hour of speed. 12 00:00:42.020 --> 00:00:43.820 That's what all the rockets are for. 13 00:00:46.040 --> 00:00:47.500 - We're using a weather balloon. 14 00:00:47.500 --> 00:00:49.560 It's a large one, actually, today. 15 00:00:49.560 --> 00:00:51.420 We're going as high as we can with this payload. 16 00:00:51.430 --> 00:00:53.540 It's very cold on the way up. 17 00:00:53.540 --> 00:00:56.960 It gets warmer as you approach that sort of altitude. 18 00:00:56.960 --> 00:00:59.650 So it's coldest just above the jet stream 19 00:00:59.650 --> 00:01:02.580 and then getting slightly warmer again. 20 00:01:02.580 --> 00:01:06.690 It gets back down to about zero about where the balloon will pop. 21 00:01:06.690 --> 00:01:10.220 - The idea that all those publicity stunts actually made it to space 22 00:01:10.220 --> 00:01:14.440 is helped by the fact that the fish-eye lens on some of the cameras that they use 23 00:01:14.440 --> 00:01:18.130 means that the curve of the earth looks a lot more dramatic 24 00:01:18.130 --> 00:01:19.910 than it really is at that height. 25 00:01:19.910 --> 00:01:21.940 Now we're using cameras that correct for that, 26 00:01:21.940 --> 00:01:26.290 so what you'll see on screen is more or less what you'd see up there. 27 00:01:26.290 --> 00:01:30.530 So we're not saying "space", we're saying "the edge of space". 28 00:01:30.530 --> 00:01:33.960 Which is basically just a marketing term, but the atmosphere's so thin up there, 29 00:01:33.960 --> 00:01:37.930 about 1% of the pressure at ground level, that it's close enough. 30 00:01:37.930 --> 00:01:39.470 Why garlic bread? 31 00:01:39.470 --> 00:01:41.140 Because it's delicious, 32 00:01:41.140 --> 00:01:45.400 and because someone already sent pizza up in a balloon a few years ago. 33 00:01:45.400 --> 00:01:47.610 - This garlic bread is delicious. 34 00:01:47.610 --> 00:01:49.680 It's homemade. Well, apart from the baguette. 35 00:01:49.680 --> 00:01:53.310 I did some homemade garlic butter on there with some real nice Parmesan on it. 36 00:01:53.310 --> 00:01:56.440 Although I did make it at 5 o'clock this morning! 37 00:01:56.440 --> 00:01:57.930 So it's going to be in near-vacuum. 38 00:01:57.930 --> 00:01:59.760 It's going to be possibly frozen. I mean... 39 00:01:59.760 --> 00:02:01.950 We're going to send half up in the sky with the balloon 40 00:02:01.950 --> 00:02:05.810 and then leave half on earth for a real comparison taste test. 41 00:02:05.810 --> 00:02:08.660 - As it goes up, the atmosphere is getting thinner and thinner 42 00:02:08.660 --> 00:02:10.560 and there's less and less air pushing in. 43 00:02:10.560 --> 00:02:13.140 The balloon itself will get bigger and bigger. 44 00:02:13.140 --> 00:02:16.200 So eventually the balloon will pop 45 00:02:16.200 --> 00:02:20.250 and the equipment will parachute down to the ground 46 00:02:20.250 --> 00:02:22.354 and we'll go and recover it. 47 00:02:37.870 --> 00:02:42.720 We normally predict the landing spot to within about five miles 48 00:02:42.720 --> 00:02:44.563 when we launch the balloon. 49 00:02:44.563 --> 00:02:48.180 We're tracking the balloon using some radio trackers. 50 00:02:48.180 --> 00:02:51.620 They send a signal with a GPS position to the ground 51 00:02:51.620 --> 00:02:56.860 and that's put on a map and we chase the balloon's predicted landing spot. 52 00:02:56.860 --> 00:02:59.410 I've done lots of high-altitude ballooning. 53 00:02:59.410 --> 00:03:01.810 I've been doing it now for about 10 years. 54 00:03:01.810 --> 00:03:05.560 Never lost one. Sent one to its doom a couple of times. 55 00:03:05.560 --> 00:03:08.103 - All sorts of food items have been launched into the stratosphere. 56 00:03:08.103 --> 00:03:10.670 The BBC sent wedding cake up as part of a children's show 57 00:03:10.670 --> 00:03:13.970 but the punchline at the end was that no one actually ate it. 58 00:03:13.970 --> 00:03:17.700 I've yet to find any balloon-launched food that was actually eaten after landing. 59 00:03:17.700 --> 00:03:19.809 And the main reason for that is you have no idea 60 00:03:19.809 --> 00:03:21.970 where it's going to land, what it's going land in, 61 00:03:21.970 --> 00:03:25.410 or what animals will have got to it first. 62 00:03:25.410 --> 00:03:29.310 - The box I've designed has a GPS and a little servo, 63 00:03:29.310 --> 00:03:31.830 and a piece of string and some springs. 64 00:03:31.830 --> 00:03:36.683 As it comes down it closes the servo 1000 metres above the ground. 65 00:03:39.610 --> 00:03:42.963 - So now we have to get in our cars and go chasing the payload. 66 00:03:46.962 --> 00:03:50.000 It's just coming in to land somewhere about half a mile ahead 67 00:03:50.000 --> 00:03:51.960 so, Barry, keep your eyes on the sky. 68 00:03:51.960 --> 00:03:53.610 I've got to keep my eyes on the road. 69 00:03:56.140 --> 00:03:57.890 You reckon we're okay to park here? 70 00:03:59.380 --> 00:04:00.213 Let's go. 71 00:04:04.900 --> 00:04:08.320 - It's just on the end of that row there. 72 00:04:08.320 --> 00:04:09.420 - Let's do it. 73 00:04:09.880 --> 00:04:12.860 - Oh dear! - I think this is the way. 74 00:04:14.780 --> 00:04:16.580 Well, at least we've got two cameras, I suppose. 75 00:04:19.960 --> 00:04:21.783 Yay, I think they're still running. 76 00:04:23.720 --> 00:04:25.424 - Oh,there we go. - Lift it up, oh. 77 00:04:25.424 --> 00:04:26.803 - Oh, yes! - Yeah. 78 00:04:27.820 --> 00:04:29.620 - Alright so this is your original? 79 00:04:29.620 --> 00:04:31.160 - Yeah, yeah. 80 00:04:31.160 --> 00:04:32.230 - That's really good. 81 00:04:32.230 --> 00:04:33.750 - Not bad, right? 82 00:04:33.750 --> 00:04:34.793 - Space bread... 83 00:04:35.880 --> 00:04:36.760 - Is it cold? 84 00:04:36.760 --> 00:04:39.320 - It's not that much... oh! 85 00:04:39.320 --> 00:04:41.680 No, that tore completely differently. 86 00:04:41.690 --> 00:04:44.900 So that one ripped; that one went [tearing sound]. 87 00:04:44.900 --> 00:04:46.720 This one went click. 88 00:04:46.720 --> 00:04:48.360 - It's definitely got an icy middle. 89 00:04:48.360 --> 00:04:49.233 - Oh wow. 90 00:04:50.580 --> 00:04:53.460 - I don't know. I mean... - That has been frozen. 91 00:04:53.460 --> 00:04:54.350 That's been frozen in the stratosphere. 92 00:04:54.350 --> 00:04:56.654 - You can sorta see the colour of the middle of them. 93 00:04:56.654 --> 00:04:57.580 It's whiter, isn't it? 94 00:04:57.580 --> 00:05:00.080 - This went to the stratosphere and I'm eating it! 95 00:05:01.860 --> 00:05:02.860 Sort of. 96 00:05:03.240 --> 00:05:06.360 Thank you very much to Steve Randall from Random Aerospace 97 00:05:06.370 --> 00:05:09.040 and to Barry Lewis from My Virgin Kitchen. 98 00:05:09.040 --> 00:05:11.610 I don't actually know what I did on this. 99 00:05:11.610 --> 00:05:13.600 I'm basically DJ Khaled at this point. 100 00:05:13.600 --> 00:05:15.360 - Yeah! Yeah. 101 00:05:15.360 --> 00:05:17.570 DJ Garl-ed?
