The balloon in the beaker was purchased from a large card retailer , I have recently been in contact with the company who have sent me information from their suppliers stating how biodegradable their balloons are.
Well lets find out:
The balloon has been partly inflated and the bottom half submerged in a sea water substitute. I know there should really be a control which has been placed in a vacuum with no light, as a comparison, but I think this arrangement is suitable enough to find out how fast a latex balloon will degrade in the atmosphere or underwater.
The balloon is located in a South facing room which allows a large amount of light in, this should give an adequate opportunity for the balloon to degrade, as it is the UV component of light which causes the balloon to break up.
Some might say that the window glass will stop the UV from getting through, well I know there is still enough getting through, having had numerous plastic bags fall apart after being left in the same location in the past.
Bookmark this page and come back later to see how it is progressing.
Do you want to help make company's take more care over their balloons being lost into the environment?

65 days and the balloon has finally bursts below the water line, causing the bulge on the right.
180 Days The sections of the balloon which are covered in graphics are still intact, though turning white due to oxidation. Would still be lethal to any animal which ingested it.
