1
About 70 ,000 litres.
2
And yes, those are real people flying under real helium balloons, but if you just want to know the answer to how much helium you need to lift a person, while an average adult weighs about 70 kilos,
3
in normal conditions, one litre of helium will provide enough lift for about one gram, so you'd need about 70 ,000 litres.
4
Proving that, and finding out how this is done safely, and how you can also have a go, that's the rest of this video.
5
I've wanted to do something like this for years, of course I have.
6
I think lots of people have dreamt of flying away on balloons, but as far as I knew, the logistics and safety required made it impossible, unless you had a ridiculous budget.
7
And then, someone told me about Aeroplume in France, and the budget dropped to 60 euros for a ticket.
8
So the rest of this video isn't going to be scripted, it's just me, one of the team here holding my camera, and about 70 ,000 litres of helium that's going to lift me up.
9
This hangar was built in 1919.
10
It was used first for the blimp, to surveil and fly over the coast to detect the enemy submarines and in 2000 he goes out of the military domain.
11
Be careful to your head.
12
Oh yeah that is that's that's solid okay.
13
The history of the aeroplume starts maybe more than 20 years ago.
14
That's a blimp who was created by a man who was called Jean -Pierre David.
15
He was a French artist.
16
That was much easier than I thought it would be.
17
He discovered the world of the blimp and felt in love, and so because he's an inventor,
18
an artist, an engineer, he decided to create his own blimp, big enough to allow him to fly by beating the wings.
19
Since 2009, we propose our people to fly here.
20
The other location is a cave, 50 meters under the ground.
21
We propose the flight here during all the French school holidays.
22
So if we just let you go now what you will go on the top
23
and you won't be able to go down ever say Right, so if I want you to be free and autonome, I have to make you reach the static balance.
24
Okay, that's why Depending on your weight.
25
Yeah, I can add
26
Some little weight like this got it to your blimp in order to make you float
27
If you just take off this this oh what what is
28
happening you're just floating here just floating we have three aeroplumes here
29
and they are different by their volumes we have a bigger one
30
that can carry up to 90 kilograms we have one
31
that can carry up to 70 kilograms
32
and one can carry up to 45 now you can take
33
the wings by the black handle everything you will do you
34
will do it really slowly yep that's the same as
35
if you were swimming okay so first i will show you how to move forward You want the wings to be flat, like this, in order to go,
36
take some air and push behind.
37
Like paddling a kayak?
38
Yeah, exactly the same as in a kayak.
39
And if I want to turn, it's with one?
40
Exactly.
41
So you know how to turn, if you are doing only one wing, you will turn.
42
It doesn't react so quickly, but when it's turning, now you can take a break,
43
it will continue during a very long time there is a
44
lot of inertia yeah yeah i didn't feel like i was turning at all
45
and then suddenly i was yeah and we can also go back
46
if you want to by pushing the air on the front
47
and go flat again to go up the same as
48
if you were swimming again yeah
49
when you go forward the air is going under the wings
50
and that provides left you have to switch yeah to make the same angle
51
when you go back
52
and this is every time like this from the front to
53
the back you can feel it the air is going under the wings
54
if you want to go down it will be the opposite movement that feels
55
so natural yeah the opposite way of going up at the
56
beginning of the season we just choose to fill the blimp with 100 percent helium there
57
and with the time the helium is going out there is some leaks
58
so we can just add some more allium to compensate
59
and the really one problem here is the osmosis
60
so there is the air present outside that wants to go in the aeroplume
61
and once he's in we can't extract him
62
so the more we spend the time here the more air is inside
63
so the less he can carry once a year we have the obligation to just empty everything
64
and refill again of course we are conscious of the helium because it's very expensive and we don't want to waste helium.
65
When you don't do nothing, once you get high, the volume is going down.
66
That's because, and maybe we will repeat that after, but we made you reach the static balance and it depends on the temperature.
67
And the more higher you go...
68
I'm definitely going up quite quickly now.
69
That's why I just take off one kilogram The higher you are, the hotter it is.
70
Now you reach a new situation of static balance with a new condition of temperature.
71
Because of the slow speed of the balloon and the inertia, we have to pilot really slowly and that's why we are indoor,
72
to be protected against the wind and all the variation of the weather conditions.
73
I noticed you had a sign on the door saying make sure that the door is closed,
74
because the slightest breeze would blow me completely off course there is no problem of safety
75
because we're following you on the ground always linked by a little tether
76
but the tether is slack you're not holding me down here I'm just floating you are totally free
77
if you slow and quiet enough you will realize how to pilot
78
and have the time to anticipate so the tether is not used take some break
79
and observe that it's still turning left yeah you can rest also wow
80
if it's too late to avoid the wall
81
or the roof it will pull not for your safety
82
but for the safety of the blimp otherwise if we just touch
83
so many times it will break that's not a pressurized balloon that's just an envelope filled with helium
84
so the helium will just go out slowly it will lose his capacity to carry so the pilot will land slowly.
85
I'm amazed how calm and safe I feel right now.
86
It's happened one time here, some elements from the roof just go through the envelope and the pilot didn't notice that.
87
He was just trying to go up and oh it's difficult because the helium was going out so he landed.
88
All right, permission to land?
89
Yeah, more than 10 000 flights here in the aeroplume
90
and zero accident oh you know what I mean it's not a spot on landing
91
but I'll take it
92
if you can catch the table I'm gonna try there we go catch it got it perfect
93
so I will just take the time to link to the blim
94
and I will help you to go out it was a
95
really good flight I'm half expecting to take the table up with me here she's attached to the ground all right yeah
96

Prime impressioni: perché questo video è ottimo per parlare inglese
Questo video sulla ballooning con elio è un tesoro per chi vuole imparare l'inglese con i video! La conversazione è spontanea, con un tono colloquiale e espressioni reali, come "that's solid, okay!" o "it feels so natural". Le frasi non sono troppo lunghe, e i parlanti usano pause e intonazioni che riflettono la vita quotidiana, perfette per esercitarsi nella shadow speech. Inoltre, combina informazioni scientifiche (quanti litri di elio servono per sollevare una persona?) con aneddoti personali, mantenendo l'attenzione alta: un mix perfetto per migliorare la comprensione e la pronuncia.
Analizziamo le frasi: perché suonano naturali
- "About 70,000 litres. And yes, those are real people, flying under real helium balloons.": L'uso di "And yes" crea una connessione colloquiale, come se il parlante stesse rispondendo a un dubbio implicito. La struttura semplice, senza congiunzioni complesse, rende la frase facile da imitare.
- "That was much easier than I thought it would be.": "Than I thought it would be" è una struttura tipica per confronti nel passato, usata spesso nella vita quotidiana. La pronuncia di "easier" con la "z" soffusa e la pausa dopo "than" mostra come l'intonazione può rendere il discorso più fluido.
- "Everything you will do, you do it really slowly. That's the same as if you were swimming.": "Everything you will do, you do it" è una ripetizione intenzionale per enfatizzare un consiglio, un trucco che i madrelingua usano per rendere le istruzioni chiare. "That's the same as if" è un modo semplice per fare paragoni, utile per espandere il proprio vocabolario funzionale.
Una routine di pratica: repeat-and-record per migliorare la pronuncia
Per sfruttare al massimo questo video, prova questa shadowing routine: 1) Guarda un frammento di 10-15 secondi, ascoltando attentamente l'intonazione e la velocità. 2) Ripeti immediatamente dopo il parlante, cercando di imitare ogni suono e pausa (usare un shadowing site può aiutare a sincronizzare). 3) Registrati mentre ripeti e confronta con il video: noterai differenze nella pronuncia di "helium" (con la "h" soft) o "inertia" (accento sulla seconda sillaba). 4) Ripeti per 5 volte lo stesso frammento, poi passa al successivo. In una settimana, noterai che la tua pronuncia inglese diventa più naturale e la fluenza aumenta. Ricorda: la shadowspeak è un esercizio veloce ma efficace – anche 10 minuti al giorno fanno la differenza!
La grammatica di questo video
Le strutture che chi parla usa di più, con le parole esatte del video:
| Struttura | Nel video |
|---|---|
| Forma passiva be + participio passato — conta ciò che accade, non chi lo fa | be scripted · was built · was created |
| Present perfect have/has + participio passato — un’azione passata che conta ancora adesso | I've wanted · have dreamt |
Cos'è la tecnica dello Shadowing?
Shadowing è una tecnica di apprendimento delle lingue supportata da studi scientifici, originariamente sviluppata per la formazione dei traduttori professionisti e resa popolare dal poliglotta Dr. Alexander Arguelles. Il metodo è semplice ma potente: ascolti un audio in inglese di madrelingua e lo ripeti immediatamente ad alta voce — come un'ombra che segue il parlante con un ritardo di solo 1–2 secondi. A differenza dell'ascolto passivo o degli esercizi di grammatica, lo shadowing costringe il tuo cervello e i muscoli della bocca a elaborare e riprodurre simultaneamente i modelli di discorso reale. La ricerca dimostra che migliora significativamente la precisione della pronuncia, l'intonazione, il ritmo, il discorso connesso, la comprensione dell'ascolto e la fluidità del parlato — rendendolo uno dei metodi più efficaci per la preparazione alla prova di speaking dell'IELTS e per la comunicazione reale in inglese.
