Because its mass is being largely supported by the water. As an illuminating example, see that if the mug were made of styrofoam, and full of water, it would actually possess negative weight immersed in water, while retaining all of its mass.

No, the water inside the mug won't appear lighter. The perceived weight of the mug may seem less due to the buoyant force acting on it in water, but the water itself won't change its color or weight when viewed inside the mug.
When the mug is placed in water, it displaces an amount of water equal to its volume. The buoyant force acting on the mug is equal to the weight of the water it displaces, which partially cancels out the weight of the mug itself. This makes the mug feel lighter when submerged in water compared to when it is out of the water.
It is easier to lift a bucket full of water underwater because the buoyant force acting on the submerged bucket reduces the effective weight you have to lift. This buoyant force is equal to the weight of the water displaced by the bucket, making it feel lighter to lift.
When the mug is underwater, the buoyant force acting on it reduces the effective weight of the mug, making it feel lighter. However, when you lift the mug out of the water, the buoyant force is no longer counteracting the weight of the mug, so it feels heavier. This difference in perceived weight is due to the buoyant force exerted by the water on the object.
A rubber ball rises up in the water because it is full of a substance (rubber) that is lighter than the same volume of water. A hot air balloon rises up into the cool air because it is full of a substance (hot air) that is lighter than the same volume of cool air. The hot air balloon floats in cool air, just like the rubber ball floats in water.

because a soda can is full of air. Air is lighter than water, and is therefore boyant and the can floats.

This means it's out of fluid. Trash it. Or if it is an ACE lighter and appears to be half full, its the water you bought.
Either by drinking milk or water
Drink n find out?
They put on an act to suck you in. They mirror you. Deep down inside they are full of rage, etc., and cannot feel. They feel through the way you respond.
it gets rid of its extra water by skirting it out when every it gets full or has to much water inside it
half of the can or full can. if we keep a little water ,it can move because it is lighter ,if it is heaviour it can't move.
to close the water inlet after the cistern is full
If the jar is not completely full of water, and the air inside is not completely saturated, then yes, a little bit can.
