Which helium tank is right for you? Our large 14.9 cubic foot Balloon Time helium tank fills up to 50 9-inch latex balloons, or 27 18-inch foil balloons. Our small 8.9 cubic foot helium tank fills up to 30 9-inch latex balloons, or 16 18-inch foil balloons. And our helium tank kit offers a small 8.9 cubic foot tank pre-packaged with 30 assorted color latex balloons and a spool or ribbon – a party-阅读y piece of equipment that saves you a trip to the store. All helium tanks are portable (take them virtually anywhere, just not on a flight) and disposable – 简单 throw them out or recycle them when the event is done. They're ideal for school carnivals, holiday picnics, and back yard barbecues; also for outdoor wedding receptions using balloon bouquets as decorations. Keep them on hand for giant balloons that need refills; as always, any leftover helium is there for your entertainment, perhaps for a karaoke contest to see who can hit the highest note?
