I asked about this scenario under General Chemistry after having some questions asnwered there about glycerine, but then thought that this may be organic chemistry. I'm wondering what the necessary application of glycerine to a pond of around 3 million gallons would be to maintain a very low surface tension. Would there be organisms in the pond that I'd need to consider that may eat the glycerine? Obviously there would be rain and snow water to consider. With that being said, could I encapsulate the glycerine for long term controlled release? And what would I use to encapsulate it?
