The latex balloons used for steering can compress helium way more (per water volume) than a mylar wall party balloon. For that matter, those 100g Scientific Sales balloons i have used (nominally also called 36", I think) will take (it seems) double or more the helium moles compared with the popular lighter latex balloons, espcially those final 2 or 3 three inches of diameter to get a manly pull. Time for me to ditch the 100 gram style.

Hi Tom,
Wow, that would not of been my guess, your numbers show the size difference is 31.8 so that .84 cents for the helium to fill a dollar store balloon. I am sure the mylar balloon is very inexpensive, so it appears the dollar store isn't losing money, like I originally thought. Thanks for the data on the volume of each balloon.
Cheers,
Kurt

Kurt, An 18” foil balloon holds .44 cf of helium vs 14 cf for a 36” latex steering balloon.

The Dollar Tree in my area is selling mylar balloons which float for a buck, there not as big as a 36" balloon but not 27 times smaller, so how are they able to do this at the cost of helium these days?
Cheers,
Kurt

So at approximately 14 cubic feet per 36 inch latex balloon. Six balloons per tank. That’s $27 per balloon if anyone wants a balloon filled.

Just throwing some info out for all. I had my two 80 cubic foot tanks
refilled after the Kent contest (actually its a bottle swap not a
"refill"). It was $167 a bottle and took 2 weeks to get. They had to be
ordered but at least I was able to get some. I recall the $32 refills
when I first got the tank, then was about $50-$60 for many year until
the recent helium shortage and then went up to $115 (about 2 years ago)
and now $167. Hydrogen filled steering balloons anyone? :-)
