Boyle's Law Diving Science #1

It is one thing to tell new divers about Boyle's Law but it is another thing altogether to show them. In this video we want to show you what happens to the lungs, and air contained in therein, when a freediver descends to 14m. To do this we used an empty soda bottle, an orange balloon, and a freediving videographer




Experiment TASK:
to sink different thinks with air inside to a botom 14m of Vortex Spring.
1) Empty 2 Liter bottle with open cork
2) Orange baloon
3 Empty bottle again.
note
===== freediver found a problem with equalasing while having staff (bottle and camera) in two hands===
There for; in experiments 2) and 3) showing bottle/ballon only from botom

Experiment assistant and director;
Miss Gidds

Camera operator and freediver;
Nik Vatin

Spectators;
some SCUBAs and fish.

Water temperature +19,5*C
Central USA time 10am

if u cut the wire , how fast will it go up =) ??

[sofabike]

Do U mean wire what conects bottle to a sinker?

[freefrederikfree]

@sofabike Yes?

[sofabike]

@freefrederikfree Yes in absolute pressure it 2,4 But we have to account 1 atmosferic pressure too, what is on a water surface.

[berserkus]

I saw there was a weight attached to the bottle. I guess as the pressure rises, air inside the bottle gets squeezed and the bottle looses its floating capacity, so there must be some point from which this bottle with a weight would start drowning, withoug a hope of coming up again :)

[sofabike]

There is ALWAYS HOPE and I always in Vortex Springs Water

We'll be famous soon! :-p

[chaiti27]

very very cool !! so i guess the same level of pressure is on the lungs too

[freefrederikfree]

at 14 m , it is 2,4 bar right ?

[sofabike]

Other changes what happens is= Colors change. Orange baloon changes colors on 14m deep

[sofabike]

Yes, you'r right. On a 10m deep pressure is doble. The botom near brick-anchor is 14m deep. You may see water level in a bottle more then a half
