gasworld reports on the impact that the helium shortage has had on helium ballooning as an adventure sport.

Rising helium prices are likely to cut down on the demand for this type of ballooning, as the cost to fill a helium balloon has gone from about $3,000 two or three years ago to around $12,000. Some have proposed that switching to hydrogen-based gas ballooning could be one way for the sport to survive in the US.
