To lift a person using helium balloons, you first need to understand how much lift each balloon provides. A standard party balloon has a volume of about 11 liters and can lift approximately 14 grams (0.014 kg) of weight.
A typical adult human weighs on average around 70 kilograms. To calculate the number of balloons needed to lift a person, you can use the following formula:
Number of Balloons = Weight of Person (in kg) / Lift per Balloon (in kg)
In this case, that would mean:
Number of Balloons = 70 kg / 0.014 kg ≈ 5000 balloons.
So, it would take approximately 5000 standard helium balloons to lift an average adult person off the ground. However, there are other factors to consider, such as the weight of the balloons themselves and any additional gear the person might be wearing. Therefore, it’s always good to err on the side of caution and calculate a few extra balloons for safety!
