Not so serious question of buoyancy

[kjundvr]

Ok so some may not find this appropriate however I think that it is relevant and should be taken into consideration when diving. For the past few months I have had an ongoing battle with some buddies of mine over a question of buoyancy.

We have argued over the question: If you pass gas in a dry suit while diving does it change your buoyancy? (Magnitude does not matter)

One of my buddies and I say it does the others say it does not.

Any thoughts?

Don't know if I am qualified, I always dive wet (Lucky to live in Texas )
But I would say does not , total volume of suit does not change.

The gas has already expanded in your large intestine to the point that it escapes. It simply moves into another container, your dry suit.

The increase in total volume of the gas escaping from the bowel is insignificant to the overall buoyancy of the diver.

Next time ya feel one coming on, grab an empty sandwich bag and see how much you can inflate it.

That could be interasting to explain to my fiancé

If the gas is created during the dive such as by fermentation of certain foods in your GI tract then the buoyancy shift took place at that time. The passing merely transfered it to the suit space.

In the most infinitessimal aspect??? Yes.
But who really cares?

In theory also, there is going to be a small temperature change from within your GI tract to your drysuit, so the cooling effect will reduce the volume of expansion that was created during the creation of that gas (through the processes such as fermentation as mentioned before). With the slightly lower volume, that will reduce the added buoyant effect of the gas' creation, albeit near negligible I suppose.

Very funny thread...Many more comments to come I am sure.

Try striking a match and see if you explode or just shoot fire out the seals.......

As long as I'm downwind when he unzips that baby, I don't!

I dont really care at all. But it's one of those funny things to ponder while waiting for you computer at work to process data.
