Archimedes' principle states that the apparent loss in weight of a body that is totally or partially immersed in a liquid is equal to the weight of the liquid displaced.

 

Archimedes supposedly formulated this principle after stepping into a bath and watching it overflow. According to legend, he became so excited that he ran out into the street naked shouting "Eureka! Eureka" ("I've found it! I've found it!").
