How much helium does it take to lift 1 gram?
The density of helium is equal to 0.1785 grams per liter. The density of air, on the other hand, is about 1.25 grams per liter. Leaving some tolerance for the weight of the balloon and the string, we can approximate that every liter of helium has a lifting force of one gram.
How many balloons will it take to float a toy car?

Is it possible to fly with balloons?
A Successful Attempt at flying with balloons. There are a few people in the world who have successfully flown by use of balloons. The most notable was Tom Morgan in 2011. It took 100 giant balloons and two days of blowing them all up.
Can you float with balloons?
The helium balloon displaces an amount of air (just like the empty bottle displaces an amount of water). As long as the weight of the helium plus the balloon fabric is lighter than the air it displaces, the balloon will float in the air.
Can you really float with helium balloons?
Although helium can easily float the weight of the balloon and string, its lifting power is actually quite small: a helium balloon that is one foot around can only lift about one-half ounce. If our cartoon baby weighs about seven pounds, he or she would need over 200 one-foot balloons to even begin to lift off.
How much helium do I need for 100 balloons?
If you’re trying to inflate 100, 9-inch standard latex balloons, you will need approximately between 25 to 27 cubic feet of helium.
How many balloons can a tank of helium fill?
Large Helium Tanks for Sale A large 14.9 cubic foot Balloon Time® helium tank fills up to 50 9-inch latex balloons, or 27 18-inch foil balloons.
Why can a small helium tank fill so many balloons?
How can such a small tank contain enough helium to fill so many balloons? Answers will vary. [The tank can hold enough helium because the gas in the tank is under tremendous pressure. When the helium goes into the balloons, it occupies much more space because there is less pressure in the balloons than in the tank.]
