This is called buoyancy. The same relationship holds true with a vessel floating on a sea of sulfur hexafluoride. However, since SF 6 is still a gas and is less dense than liquid water, the floating object has to be much lighter to stay afloat. This is why invisible water experiments typically involve light boats made from a sheet of tinfoil.

Lift rate is the rate at which an object rises due to the lifting force of helium. It depends on factors like the lifting capacity of the helium and the weight of the object being lifted.
The shape of the balloon was determined by the pressure of the air or gas (such as hydrogen or helium). In 1852, Henri Giffard built the first powered airship, which consisted of a 143-ft (44-m) long, cigar-shaped, gas-filled bag with a propeller, powered by a 3-horsepower (2.2-kW) steam engine .

The helium that is there comes from alpha particles emitted by radioactive decay (see How Nuclear Radiation Works for details on alpha decay).
