http://en.wikipedia.org/wiki/BuoyancyBuoyancy force, not weightless...When you immerse an object in water, water pushes it upwards. This is called Archimede's principal. It states, the maginitude of the upward force an object immersed in a fluid experiences equals to the weight of the fluid displaced due to that object.Keep in mind, when you immerse an object in water, it displaces water according to its shape. So, more water it displaces the more upward force it experiences.Weight is actually the downward force applied on an object due to gravity. When you immerse an object in water, the downward force is compromised by the upward force the water applies on the object. That is why objects weigh less in water. And remember, water may not totally out-weigh the object's weight. It might, sometimes, be possible, but it is not a rule.
