I wonder: How much Helium does each balloon takes and how long does each last once it's filled up?

- devindotcom 11y agoThey last about a month IIRC, and they're not particularly big - the equivalent of 15 or 20 party balloons, I would estimate.
- rtkwe 11y agoThey're supposed to last ~100 days and are pretty large. The time was one of the big points they had to address to get the economics right. The balloons had to last much longer than a normal balloon would. https://lh3.googleusercontent.com/-1EOC6WWfgA8/UbvU_yFNsKI/AAAAAAAAAFA/qTKWiy0SsFc/w1223-h815-no/00E.jpg https://lh3.googleusercontent.com/-1EOC6WWfgA8/UbvU_yFNsKI/A...
