What is the force of a balloon?
For a one cubic foot helium filled balloon , gravity pulls the down on the helium with a force of 0.0114 pounds while the air pushes up with a force equal to the weight of the air the helium displaced, or 0.0807 pounds. The difference in the up and down force is 0.069 pounds.
What is the force of floating?
An object will float if the buoyancy force exerted on it by the fluid balances its weight, i.e. if FB=mg F B = mg . But the Archimedes principle states that the buoyant force is the weight of the fluid displaced. So, for a floating object on a liquid, the weight of the displaced liquid is the weight of the object.
What is the buoyant force on a helium balloon in air?
1g per litre
How much weight does a helium balloon lift?

How many balloons would it take to lift a house?
(Most houses weigh between 80,000 and 160,000 pounds.) Given that 1 cubic foot of helium can lift 0.067 pounds, it would take 1,492,537 cubic feet of helium to lift the house—or about as much as would be contained in 105,854 balloons, each 3 feet in diameter.
How much does it cost to fill a large helium tank?
Prices vary, but you can expect to pay about $40 for the smallest size, and $250 for the largest. They typically require a cash or credit card deposit that ranges anywhere between $100 and $200. The deposit is returned to you when you bring back the tank in working, empty condition.
How much does it cost to inflate balloons with helium?
In general, you can expect the following price ranges to fill balloons with helium: Latex balloons: $0.99 to $1.29. Foil balloons: $1.99 to $15.99, depending on size.
