Really people, it took me 30 seconds of research to find this….do u really think 5 balloons could lift a pom at the same rate straight up??? I knew the answer to this already but also knew people wouldn’t believe common sense so I found the stats. If you weigh 50 kilograms (about 110 pounds), then you weigh 50,000 grams. Divide your 50,000 grams by the 14 grams per balloon and you find that you need 3,571.42 balloons to lift your weight. You might want to add 500 more if you actually would like to rise at a reasonable rate.
