Helium shortage deflates grad parties
Getting pumped for graduation?
Not if you're trying to fill a balloon with helium.
You'll likely have trouble floating this year's graduation balloons because of a nationwide shortage of the lighter-than-air gas that, so far, is hitting only the party décor industry.
Not hospitals, which use helium for operations and to cool down high-powered scanners. Not welders of stainless steel, who use the gas to keep their welds smooth. Not manufacturers of goods as varied as flat-screen TVs, fiber optics, solar panels and rocket fuel.
