How To Make Your Lungs Explode When Scuba Diving
Summary
TLDRThis video demonstrates how air volume changes with depth when diving. Using a plastic bag to mimic lungs, it shows air compression and expansion underwater. Free divers hold a constant volume of air, but scuba divers carry an external source, which can lead to lung rupture if not managed properly. The video emphasizes the importance of breathing out during ascents to prevent injury and encourages taking a certification course for safe diving practices.
Takeaways
- 💡 When you dive, the volume of air in your lungs changes due to water pressure.
- 🌊 At the surface, the air in the lungs (or a plastic bag simulating lungs) is fully inflated.
- 📉 As you swim down, the increased water pressure compresses the air, making the lungs feel softer.
- 📈 When ascending, the air in the lungs expands again due to decreased pressure.
- 🤿 Free divers hold their breath at a constant volume of air throughout the dive.
- 🤿 Scuba divers carry an external air source, which expands as they ascend.
- ⚠️ Holding your breath while ascending with scuba gear can lead to lung rupture.
- 🩺 Lungs won't explode but can rupture, allowing air to leak into the chest cavity.
- 🏊♂️ It's crucial to breathe out gradually while ascending to prevent lung damage.
- ⏰ Holding your breath at a constant depth while scuba diving is safe and not dangerous.
- 📚 The video encourages taking a certification course for safe diving practices.
Q & A
What does the plastic bag represent in the video?
-The plastic bag represents the lungs, illustrating the changes in air volume as one swims up and down in water.
Why does the air in the plastic bag get compressed when the host swims down?
-The air in the plastic bag gets compressed due to the increase in water pressure at greater depths, which reduces the volume of the air inside.
What happens to the volume of air when the host swims back up to the surface?
-When the host swims back up to the surface, the air in the plastic bag expands again because the water pressure decreases, allowing the air to fill the bag completely.
Why is it important to breathe in and out during a scuba dive?
-It is important to breathe in and out during a scuba dive to prevent lung rupture from the expanding air volume as one ascends, which can lead to serious injury.
What is the difference between free diving and scuba diving in terms of air volume management?
-In free diving, the volume of air in the lungs remains constant as it is the air breathed in at the surface. In scuba diving, an external air source is used, and the volume of air can double from depth to surface if not managed properly.
What is the risk of holding one's breath while ascending in scuba diving?
-Holding one's breath while ascending in scuba diving can cause the lungs to rupture due to the rapid expansion of air, which is dangerous and should be avoided.
Why does the host mention that lungs won't 'explode' but can rupture?
-The host clarifies that lungs won't explode like a balloon, but they can rupture if the pressure inside them becomes too great, such as when holding one's breath while ascending.
What demonstration does the host use to show the risk of holding breath while ascending?
-The host uses a plastic bag made from ice cubes to demonstrate how the bag can rupture and leak air when ascending from the bottom to the surface while holding breath.
What is the advice given for those planning to go scuba diving or diving in any way?
-The advice given is to take a certification or a course to ensure safety and awareness of the risks and proper techniques involved in diving.
Why is it not dangerous to hold one's breath at a constant depth while scuba diving?
-Holding one's breath at a constant depth while scuba diving is not dangerous because the pressure is consistent, and the volume of air in the lungs does not change significantly.

🌊 Effects of Pressure on Air Volume During Diving
This video demonstrates the impact of water pressure on air volume, using a plastic bag to symbolize the human lungs. At the water's surface, the bag is inflated with air, representing full lungs. As the presenter swims downward, the increasing pressure compresses the air, causing the bag to deflate. Upon returning to the surface, the air expands, and the bag re-inflates. This illustrates the principle that a diver's lungs maintain a constant volume of air during a free dive, inhaling at the surface and exhaling as they ascend. The video contrasts this with scuba diving, where an external air source allows for greater volume changes with depth. It warns of the dangers of holding one's breath while ascending, as肺部扩张过度可能导致肺部破裂。 The presenter uses a plastic bag made of ice to visually show how air can rupture the bag, mimicking a lung rupture. The video concludes with a recommendation for diving safety through certification and education.

Transcripts
this video i will show you guys what
happens to the volume of the air when
you swim up and down in the water
to illustrate this i will use this
plastic bag which represents your lungs
so you can see at the surface i'm
inflating the plastic bag so it's
completely full of air and then i'm
sealing it at the bottom
now when i swim down to the bottom of
the pool you can see that the air is
getting compressed and the
plastic bag gets soft again
and when i go back up to the surface you
can see the air expands again and then
you can see it's completely full of air
this is actually exactly what happens
when you're free diving because you have
a constant volume of air inside your
lungs when you die
that's because you breathe in at the
surface and then you hold your breath
while you swim down and come back up to
the surface so it's the same amount of
air throughout the whole dive
but when you're scuba diving you are
bringing with you an external air source
down to the depths that means
if you breathe in at 10 meters
and then hold your breath all the way up
to the surface
that air that was 5 liters at the bottom
will now be 10 liters of volume at the
surface
but since your lungs can only expand so
much what will happen is you will
rupture your lung your lungs won't
explode like you saw in this first
picture
but
they will rupture and it the air would
start leaking into your chest
outside of your lungs
you can see this with this plastic bag
made from making ice cubes
you can see that i start at the bottom
and when i get about halfway up to the
surface it has ruptured because of the
expanding air and you see the air
leaking out you can't die from this
so it's really important that you
breathe out through the whole dive when
you're swimming up
if you're staying on the same level in
the water then it's not a problem
because you can stay at 10 meters you
can take a deep breath with a scuba
diving tank and then hold your breath
for a minute it's not dangerous in that
way
same if you're swimming down it's not
recommended but it won't cause your
lungs to rupture
but when you swim up then you get in
trouble if you hold your breath i hope
you learned something from this video
and uh if you are planning to go scuba
diving or diving
in any way please take a certification
or a course to make sure that it's 100
safe what you're doing there's a lot of
things you don't know about diving if
you haven't taken a course so if you
like this video just subscribe to this
account hit the little bell and you will
get a notification next time we upload a
video about diving or scuba diving free
diving swimming or whatever
have a nice day
