IRCWCC was playing with an idea a few years back. Take a toy punching balloon from the grocery store. It was fairly heavy rubber with a loop at the top to hook up a rubber band to. Put a plug in the intake that has a grove to hold a tie wrap. The plug gets a hole tapped for 10/32 and a clippard barbette. All you need is a popette and some hose. Hit that channel and the co2 flows into the balloon!
I think the idea was to actually mount this in a channel cut into the bottom of the hull so the balloon had space. Would be super cool if we could figure out how to use the sink to change a switch from co2 goes to gun to co2 goes to balloon.
One of the problems with email lists is that there is no searchable archive for the stuff that got talked about a couple years ago. 
I can just imagine this...
1/ it fills up with air
2/ it floats the ship
3 the ship rises to the surface
4/ It farts!!!
5/ back to the bottom
