Workers employed by the balloon store owner use helium mixed with aluminum, caustic solutions and water as pressure or purge gas to keep balloons afloat.
To prepare for the event, the Balloon Festival store, on 2109 McCulloch Blvd, has changed its hours this month with the arrival of new volunteers.
KIDAPAWAN CITY, Philippines - Two were hurt when a cylinder filled with helium exploded in the house of a balloon store owner Friday night, causing panic among city residents who first thought it was a bomb set off by terrorists.
McKnight said that 12 to 15 volunteers have been signed up to work at the Balloon Festival Store this fall, with the help of volunteer coordinator Richard Kerber. McKnight expects more volunteers to follow, and two of the store’s staff will be dedicated toward the task of helping them volunteer as well.
