How Long Can You Hold your Breath?

[GasX]

this long?

 

[Eli]

Wow.

How does he sink like that in the water?

 

[GasX]

The deeper he gets, the more the pressure shrinks his lungs and the less buoyant he becomes.

 

[alkemyst]

depends how hot she is.

woweeee

those fins on that diver were wiiiiide.

Those single fins are bizarre but I hear you can dolphin kick like Phelps with them on.

They are allowed to use weights, but they must keep constant weight, meaning they can't drop the weights at any time during the descent.

I can hold my breath forever. 🙂

Did you watch the video? He is wearing a swim cap, mask and a speedo.

Imo, the trick to swim and still stay under water for so long is to be relaxed, never struggle, keep the heart rate low. I can swim underwater for about 35-40m but while not moving, I can stay underwater easily over a minute. I haven't taken time in a while though.

They were hidden in the speedo. 😉

I would have died before I made it to the bottom of that descent, rofl.

bout tree fiddy

heh, I dove the blue hole. Nice place.

The reason he sinks so fast is once you're past about 30 feet you are no longer boyant and are actually heavier than water because of the pressure.

Another trick to stay under for a long time is to put on a 50lb weightbelt

Weird. Never heard of this phenomenon.

Would the same apply to something like a basketball? How exactly does this work? lol

Is it just that the amount of air in your lungs is small compared to the weight of the rest of your body?

The diver takes a deep breath at the surface (1 ATM) and goes under with effectively two inflated balloons in his chest. when he gets to ~30ft the pressure has doubled (2 ATM) and (according to Boyle's law) the volume of air in his lungs has halved and consequently he has less buoyancy. Every 30ft, the pressure goes up by 1 ATM and the lungs get smaller.

So, to answer your question, yes. A basketball will deflate if it is pulled down to depth. Inversely, if you inflated a basketball at 100ft, it would expand and explode as it got near the surface. The phenomenon leads to the first rule of SCUBA - never hold your breath - especially when coming up.
