Effervescence at depth

Contents of an egg are fluid therefore not compressible.

personally i would like to know how to blow the bubble rings you see divers do - but i guess it helps if youre a smoker

Yeah, I've seen those. I'd also love to be able to do it. I tried it once but the inverted body position plus my inexperience lead to me becoming rathing sick under water. Maybe I'll try it again.

That's if it were an ideal fluid, which I doubt it is. I'd be very surprised if you could take an egg down to the bottom of the marianas trench without it breaking under the pressure.

Ah I was thinking of the inside fluids. There is an air pocket that would lead to shell breakage at some depth.

Get on your back with your mouth up. Take a gulp of air before removing the reg. Parch your lips then say "POP." Reinsert reg. With a little practice you can blow two or three rings in rapid succession with each ring inside the other.

You make it sound so easy Just explain what "parch your lips" mean please. Sorry if I'm being silly but maybe it's just because English is not my native tongue.

I'm not a smoker, but I'm pretty good at bubble rings. Basically you face the surface, and make a "puh" sound with your mouth. After doing a few, you figure out the exact way to do it.
