Has anyone tried to use hi-float then twisted aballoon to see how long it would last or is the normal 260 not recoomneded to be used by hi float. I am not able to find a lot of information on hi-float and 260's most of the information is about rounds hearts geo's and donuts???

You normally put hi-float into a 160/260 with just air or nitrogen to make the balloon hold the quantity of air inside for longer, if making a dress it would last 5/7 days rather than 2/3 without. A 260 will not float with helium inside, well possible just for 30 mins but with the added weight of the hi-float then not even for a short time.

Thank you for you r response do you have any measure ments on how much hi float to put in a 160/260/350 as stated above all I can find is how much for a round or heart etc.

Sorry, no idea. Just trial and error.

Hi float makes a injector for pencil balloons.I was able to see them at Alternajam. Not sure if they are commercially available right now.Check the site. I have never used one, so can not comment any further.Good luck.

Looking around it does not seem to be available. Maybe checking with Don C. or Tod N.could lead you in the right direction.

I tried my best to win one t AlternaJam but T_T no dice.

Sounds like a nightmare. A little hi-float goes a long way. If it gushes over, you're probably using too much. I'd think a couple of drops for a 160. Ugh, sounds messy. Good luck, find that injector!
