What is Hi-Float made out of, and is it possible to make my own?

Hi-Float is, apparently, some liquid you can pump into a balloon to make it stay inflated for a longer amount of time. I can't seem to find anything other than commercial promotion on a Google search, and I'm terribly curious about how it does this, what it's made out of, and whether it would be feasible to make it myself, homebrew-style.

The Wikipedia article on balloons states that latex rubber, from which balloons
are made of, is porous.The helium  in the balloon gets out thoughthe pores,and thus deflation occurs. Sealing the pores would prolong the ability
of the balloon to hold gas.

Idea !  (I have not tried this so experiment at your own risk people):
I'm wondering if shooting a bit of  HAIR SPRAY?  into a balloon  might
work similarly to the commercial  stuff...........

Or maybe spray the outside of the balloon once inflated?

Hmm... Or both. I might give that a try.

Brilliant site! Thanks.

According to www.fdionline.net/fdi/public/files/msds/High-Float.pdf, HighFloat's "Major Components" are "water, polyvinyl, alcohol,dextrose monohydrate"

A quick search shows that "dextros monohydrate" is basically sugar.

I don't know if the polyvinyl and alcohol are in the form of "polyvinyl alcohol", but if they are, then wikipedia tells us that this has "excellent film forming, emulsifying and adhesive properties".

Enough information for a little experimenting I would think.....

Polyvinyl alcohol is apparently the major ingredient in some types of eye drop.

Reading the next sentence on the wiki page:  "It is odorless and nontoxic. It has high tensile strength and flexibility, as well as high oxygen and aroma barrier properties". 
Looks like this plus some sugar water might be worth a go.

Their description sounds like what Kiteman would call"woowoo." But their warning about initial buoyancy raisesanother question: why would the balloon be not-so-buoyant at first,but then regain buoyancy later? Isn't it a closed system?
You know as much as I do about this, it probably works, but they seem tobe making an effort to push it (no surprise there). Someone did tell meabout decorating wedding tables in advance, only to find the balloonshad dropped before the dinner happened - there is a market of sorts.

I've often wondered if it isn't some kind of glue; I've seen deflatedballoons filled with Hi-Float, and they were kind of rigid.  I'msure you're run-of-the-mill glue wouldn't work necessarily, but that'smy guess.

You seem to be on the right track -- their website says it's"similar to postage stamp adhesive."
