Chamber dive today

Yeah that will truly tell the tale. Did you notice the density of the air @ 130?

 

[Marie13]

The balloons seemed very heavy.

The reason I asked, the density of the air was the main thing my buddy/wife and I noticed when we did our Deep Cert in Cozumel. It was very clear, bright and great viz those 2 days.

The balloons seemed very heavy.

Huh?

 

[Marie13]

Huh?

We had balloons we had blown up to demonstrate Boyle's Law. By the time we were at 130 ft, they seemed very heavy to me.

 

[TMHeimer]

Sounds like a cool experience.

Your dive profile looks exemplary. Perfect buoyancy and incredible descent and ascent speed control and consistency. I commend you and your instructors on you buoyancy control.

Everyone have their snorkels?

 

[Marie13]

Nope! And I dislike having to use one in class, but when you're doing stuff like surface nav exercises, there's no choice in the matter.

 

[5 Star]

Wow, that sounded like a unique experience.

Same mass in a smaller space will "feel heavier".

Yeah, that's what the "huh?" was about.
I was thinking that was probably so (what you said): It felt heavier, because the balloon was smaller at the same weight. I think the same weight at least. As a light rigid, in compressible object it should have become lighter in the heavier air, but as a balloon it was likely compressed all the same as the air... I think, thus the same weight. Just a matter of feel. Then I thought a latex helium ballon might be interesting too, to see how different Gases maybe compress differently - or the same? Long forgotten stuff that maybe I should refresh. Anyway, then, I just summarized all the wonderings to "huh?" To find out what Marie really meant.

Would be interesting to do some day.
