neat product! looks like it would cost $6-10 of the stuff to coat a 5'
balloon. folks on Amazon.com seem to think it works. I just bought some--
I'll try it out on August 8th.
I'm guessing it's PVA (polyvinyl alcohol) based, because PVA is water
soluble and is derived from PVAc (polyvinyl acrylate), the glue in Elmer's
and on lickable postage stamps. It's also a great gas barrier-- but only
when dry-- and it wicks water. we'll see how it performs.
I'm guessing from this note in the FAQ:
Yes. HI-FLOAT is nontoxic, non-irritating, non-corrosive, nonflammable, and
biodegradable. It is very similar to the adhesive found on the back of
postage stamps. Wash off the skin with water. If accidentally splashed into
the eyes, flush with water for several minutes. Although it is nontoxic, it
is a good idea to keep bottles away from small children

I was right about hi-float being PVA. here's the original patent:
http://www.google.com/patents?id=jwAfAAAAEBAJ it's a mixture of PVA, water, and dextrose, and the patent expired six
weeks ago....
