    Balloons filled with air will last for days to weeks, and can be filled the day before your function. Balloons filled with helium gas usually last less than a day, and need to be inflated on the day of your function. If you are DIY, always do a test inflation the day before to determine the flying time of the balloons under your conditions. Flying times will depend on the size and quality of the balloons, and the conditions on the day you inflate them. A standard size helium balloon is 28cm (11") and should fly for 12-18 hours. Balloons are adversely affected by heat, wind and sun, so keep them in a cool, dark place until needed. Australia is a hot country, so I am always conservative with balloon flying times, and any extra is a bonus. Don’t leave helium filled balloons in your car while you shop for the party – pay the extra for delivery or DIY at the venue just before the function. (1)

    Mathematically, it depends on several variables m = PVM/RT where: m = mass of the gas in grams P = pressure inside the balloon, in atmospheres V = volume in liters M = Molecular weight of the gas R = a constant = 0.082 T = Absolute temperature, Kelvin At sea-level, the air pressure is 1 atmosphere and say we are at room temperature. Then P = 1 and T = 293K.'

    Also, remember that you should never release helium ballons into the air. Balloons cause the death for countless numbers of sea turtles and whales. Balloons cause them to suffocate or starve to death (by blocking stomach or air valves). Also metallic balloons can cause power outages when they get caught in power lines. (2)

    Helium Latex Balloons

  • Helium balloons work by the same law of buoyancy. In this case, the helium balloon that you hold by a string is floating in a "pool" of air (when you stand underwater at the bottom of a swimming pool, you are standing in a "pool of water" maybe 10 feet deep -- when you stand in an open field you are standing at the bottom of a "pool of air" that is many miles deep). The helium balloon displaces an amount of air (just like the empty bottle displaces an amount of water). As long as the helium plus the balloon is lighter than the air it displaces, the balloon will float in the air. So It depends on the strength of the balloon, hence the reason for the foil balloons gift stores use , the life expectancy is longer than latex which seems to breakdown after a day or two ..

    I am involved in planning many events. We use helium balloons on a regular basis. We put our balloons up in the morning and they stay up until midnight or later. In order to make these balloons do this we use a Hi-float. It allows the balloons to float for a longer amount of time. I hope this helps!!
