Here's one that popped into my head....maybe you guys can help.

Let's say I'm diving a drysuit and I've achieved perfect neutral buoyancy. Without inhaling or exhaling, if I fart will I go positive and start to rise?
 
The answer - Nope. The gas still is within the buoyancy envelope - unless it eats a hole in the suit! Refer to macdiver's point on that.
 
It might change your orientation because of the gas movement. I'd make sure it doesn't vent through the front of the neck seal before running the experiment. :D
 
I know nothing about diving (though I pretend to on SB), but I would venture to guess that the gas pressure would need to be different in order to facitltate the exchange of gasses;

Hence the gas would expand as it reached the lower (relative) pressure of the suit, thereby adding bouyancy.... just my 2 psi worth ( of un-known gasses)
 
I pity the person that has to open the zip after the dive...
 
I see think this thread has more potential than the 'mask on forehead' one. This one needs to involve physics :D

Just make sure you are in propper trim, or the gas may give you floaty feet (smelly ones too!)

;)

Maybe along with a "Pee" valve dry suit manufacturers should offer a "Gas" valve.

I dare say the connector would be a pain in the arse!
