An object underwater feels lighter than it does in aor because of buoyancy.
Buoyant force acts in the opposite direction to the force of gravity so it makes the object feel lighter
They are not really lighter, they only seem lighter. Objects weigh the same in water as in air, but in the water, there is an additional force, of the water pushing the object up.
Objects underwater feel lighter than it is in the air because water density is greater then air density.
Air is lighter than water.
A floating object in water means its mass is smaller than water and therefore it floats. just like helium baloons float upward because it is lighter than air
Moist air is heavier than dry air, because of the water.
Objects are more buoyant in water than in air.

A helium balloon floats because helium gas is lighter than air. By filling a balloon with helium, the balloon also becomes lighter than air. The helium balloon floats for the same reason that objects float on water: objects less dense than water are pushed up by buoyant forces equal to the weight of water displaced by that object. What happens in water also happens in air, and the helium balloon is pushed upwards by a force equal to the weight of air it displaces.
Heavier than air objects accelerate downwards. Lighter than air objects accelerate upwards until they are no lighter than the air around them.
depends if the plastic is heavier or lighter than water and if its hold air which is lighter than water

Lighter air will rise; it is the same phenomenon as an air bubble rising in water.
Moist air is heavier than dry air, because of the water.
Water isn't "heavy." Liquid water is more dense than air, yes, but water vapor is (significantly) lighter than air. Water is a liquid at temperatures far higher than what might be expected based on its molecular weight because of hydrogen bonding.
Water constantly pushes upwards against an object making it seem lighter.
