Archimedes' principle

Archimedes' principle is something about how the boat floats on water (ボートは水に浮く) [ok, ok ....it's actually something more complicated than that but this is a draw not a Physics lesson ) .... The idea is that i sent this draw for a : Draw the Physics - competition (hope that's how you translate it ) (=^.^= ) and i won 1st place ... So I really hope you like it (oh i used crayons too - kind of my first draw when i used crayons - i wanted to try something new because usually my drawings are only by pencil)
