Let’s start by taking the person’s weight into account. A helium-filled balloon can typically support 14 grams of weight. This implies that around 5,000 balloons would be required to carry a person weighing 70 kilos. However, by using larger balloons or adding more helium to each balloon, this number can be decreased. Speaking about helium, the volume of helium inside each balloon should also be taken into account. A balloon can generate more lift the more helium it has. Depending on the size of the tank and the size of the balloons being filled, the typical helium tank has the capacity to fill up to 100 balloons. So how long is a helium tank good for? Once more, this is dependent on a number of variables, including the size of the tank and the size of the full balloons. A smaller helium tank can typically fill 50 to 100 balloons, whereas a larger tank can fill 500 or more balloons. The rate at which helium is consumed has an impact on a helium tank’s lifespan as well. The tank will run out of helium faster if the valve is left open or the balloons are filled too quickly.
In summary, the quantity of balloons required to hoist a person will vary according on their weight, the size of the balloons, and the amount of helium they contain. A larger tank of helium can fill up to 500 balloons, whereas a smaller tank can only fill up to 50–100 balloons. Remember that the rate at which helium is utilized has an impact on a helium tank’s lifespan. Therefore, use caution if you intend to hoist someone using balloons and keep in mind the aforementioned variables.
