Can some explain what is Archimedes principles?

    A body will displace it's own volume when immersed in a fluid. So, if your bath is full and you get in you'll spill your own (body) volume on the floor.

    As a bonus, "Eureka!" is Ancient Greek for "where's my towel?".

    One of the above may not be entirely true... :)

    Read the Wiki page on Archimedes, there are several fascinating bits of technology that he's associated with.

    Archimedes principle states that-"any body completely or partially submerged in a fluid (gas or liquid) at rest is acted upon by an upward, or buoyant, force, the magnitude of which is equal to the weight of the fluid displaced by the body." Means that suppose a brick is thrown in water, the brick initially sinks and looses a part of its weight, which is replaced by the buoyant force acting from below that helps keep the brick afloat. To have a better understanding, you can look up to this illustration.
