put rockets on it or attach fishing line to the top of it then put the other end on a long stick.
(mass of object)/(volume of object) ≤ 1.225 kg/m3 (this is the approximate density of air at normal atmospheric conditions - your mileage may vary)
If it less dense
no and mass is air
It could, if it contained enough air. To float on water, you would need about 1 liter of air for every kilogram you want to keep afloat.
To determine the volume of air needed to float an object, you need to know the density of air and the weight of the object. For example, if the density of air is approximately 0.075 lb/ft³, then to float a 1000-pound object, you would need approximately 13,333.33 ft³ of air (1000 lb / 0.075 lb/ft³ = 13,333.33 ft³).
Buoyant means: Tending to float on a liquid or rise in air or gas
The Object's name is an "Air Craft"If its not... Then I don't really know.
Objects filled with air float on water because the density of air is much lower than the density of water. This creates buoyant force, which causes the object to float. The air-filled object displaces an amount of water equal to its weight, allowing it to stay afloat.
you will float up in the air
Whether an object floats or not does not depend on whether it is magnetic. An object will float if it is less dense than the fluid in which it is placed.
when a object float it has density
No, it's the air volume on each item. For example, a balloon filled with air will surely float on the water, but a ballon filled with water will not float. That's because there is no air in the second one and that makes it even heavier.
