Effects of a balloon drifting in sea for 6 months
« on: July 10, 2008, 09:46:30 AM »
I would like to know the effects on a balloon (made from rubber latex or flexible PVC) if it floating in the ocean. The effects of the salty water? The effects of the large quantity of ions in the ocean? The effects of sunlight (UV)? Can anyone provide me with information about (parts of) my questions? I am especially interested in the flexibility reduction over time from the various aspects.

Is there a rescue note inside :)

As with indoor balloons, the air will seep out of the balloon over time, well before its 6-month cruise is over.  The sun might raise the temperature of the air inside the balloon, and PV=nRT will adjust the pressure and volume accordingly.

actually, I never said anything about an inflated balloon. I get that you would think this, for this is normally the purpose of a balloon. It does need to be inflated eventually, but that will be done after various time periods. So the question is regarding the material of a non inflated balloon.
