Bests & Worsts Reviews from Amazon

Hi-Float works! Hi-float is meant to be used in very small amounts. I blew up 25 12" latex balloons for my son's January birthday, and they all stayed afloat for at least 24 hours, with some starting to lose their lift after the full 24 hours, but others lasting for 48+ hours! The key is to insert the spout all the way into the "top" of the latex balloon (not just the neck of the balloon), and pump about a pea sized amount of hi-float into the balloon, and then massage the balloon to work product around with the intention of coating the inside of the balloon evenly with the hi-float gel. Very little is needed, and you want to do this just prior to inflating your balloon with helium. Follow this method, and I promise you your balloons will last for hours. This is the same product & brand that we used to use when I worked at a flower shop and we would never fill latex balloons without it. Just remember, a (very) little goes a long ways!
