Click 169 Orlando Street (PO Box 6104) Coffs Harbour NSW 2450 Tel: 02 6652 7186 Gas filled latex balloons have a limited life (6 - 16 hours depending on temperature - the cooler it is, the longer they float). They should ideally be inflated just prior to display.  The DIY Kit is the ideal solution. Inflation cost (per balloon) reduces as purchase volume increases.  You can buy even better if you buy a "Party Kit" comprising gas, balloons and clipped ribbons in matching colours. All gas bottles are supplied with a regulated "tilt " valve that makes inflation child's play.  Simply fit the neck of the balloon over the rubber Tilt Valve nozzle and tilt the nozzle sideways.  When the balloon is fully inflated - release the valve. DO NOT over inflate your balloons or you will run out of gas.  You may remember from school that the volume of a sphere goes up as the cube of the radius.  Small change in diameter - big change in volume! WARNING - Balloon gas (Helium) should only be used under adult supervision MORE > DO YOU NEED TO ORDER ANY BALLOON WEIGHTS?   DIY Party Kits - Available in mixed colours or matched to your selected colour theme - balloons, gas, clips, and ribbons.  © Balloons Plus Coffs Harbour 2011
