It's responding to the air around it. Helium floats because it is buoyant; its molecules are lighter than the nitrogen and oxygen molecules of our atmosphere and so they rise above it.
Why does helium defy gravity?
But how exactly does helium defy the laws of gravity? ... Helium is lighter than air, so a balloon filled with this gas weighs less than the air it displaces and will therefore be subjected to an upward force.
Why do helium balloons rise and fall?
The balloon rises because of buoyancy. The force (weight) of the helium plus the latex/rubber downward is less than the buoyant force of the volume of air displaced by the balloon acting upward.
