Look At This! Don’t Hold Your Breath Underwater 💀

#shorts #scuba #pressure #danger
Don’t hold your breath underwater, air expand when you go up and your lungs can literally explode for the excess of gas in them.Take a look at what happens to this bottle after we fill it up with air at 60 feet deep.

Instructor: “Don’t hold your breath”
Me: breaths in water, and drowns

"Don't hold your breath while dying"
Got it

Perfect video to explain barotrauma to my students.

I love how he showed everybody at the end that he got the cap. Good man!

[woweeeeeeeee]

I once farted at 60ft depth and when the bubble hit the surface it was very violent explosion indeed. Never hold your breath or fart while scubadiving

Air expands twice in volume every 30 feet or so that you ascend.

I had a teacher in high school who was a former diving instructor. He explained this point to one of his students profusely, as well as the need to exhale on ascent, but the kid didn’t listen. He panicked about 60 feet down and rapidly ascended to the surface with a full held breath, which resulted in his lungs literally popping. The instructor and another student dragged him through a quarter mile of sandbars and open shark infested water while administering rescue breaths as he foamed up copious amounts of blood. The kid died.

For those who wonder why it doesnt explode. Pet bottles can handle about 8-12 bar(depending on the shape) of pressure.

Everybody’s chilling until you hear:”multiple leviathan class life forms detected”

That's an interesting demonstration but no bs, my favorite part of this video is where he makes sure he retrieves the cap.

except that if youre free diving the air you take from the surface gets compressed then expands back to normal. scuba diving is different

Great demo…I’m helping my 10 year old with her junior open water, she’s going to be fine with the skills but, the classroom stuff is a bit challenging. Seeing your demo helps take the words off the page and into her mind 🙏

Love how he shows he recovered the cap to avoid backlash

edit: thanks backlash people for your feedback XD

The pressure in the bottle doesn't increase. The pressure of the atmosphere around the bottle decreases.

The only thing my SCUBA instructor called me out on was when we were sort of "let loose" in the dive pool. Slightly sleeper than normal pool, nothing 30 foot or truly deep. I was bouncing from the bottom to the top without exhaling. I knew the air would expand so I did a shallow breath and bounced. He had to call it out because this would rupture a lung if done for a greater distance.

It's also why most people surfacing off air would always blow bubbles.

This advice only makes sense if you get your oxygen while deep, and then ascend rapidly. But even then it doesnt take into account that your lungs and breathing passages are not as airtight as a water bottle, if the air in those passageways expand it would escape through your mouth and nose before it ever got to dangerous decompression levels.

It's the air in the blood system we worry about while diving deep.

Youtuber: Don’t hold your breath underwater
Me: Guess I’ll drown then

[hajimane]

Don’t hold your breath during explosions either, same result

Dangerous for humans also is N2 which also gets into the blood but does no chemical reaction whatsoever with the body in its gas form.
When you dive 20 meters down, and breathe normal air (or the gas thats in the scuba tanks), the amount of N2 increases 3 fold, because the pressure is also 3 times higher, thus the concentration of N2 is 3 times as high in the blood, which per se isnt really the problem. The problem arises when you dive up too quickly.
If you then instantly dive up, the N2 will just gas out, because the pressure decreases back to the normal partial pressure of around 791.25 hPA for N2.
--> decompression sickness

“Meester George” guy on vacation. He’s a good operator.

i remember diving to the bottom of 10-12ft pools as a kid and feeling the massive pressure on my head. good times
