If you want to have fun. Draw an iceberg and see how it will float.
Icebergs are less dense than water, so they always float with about 10% of their mass above the water. But which way up? An iceberg wouldn’t float exactly like on this page in reality. Its three-dimensional distribution of mass and its relative density compared to the water are both significant factors that are only approximated here.
