Why does something big (battleship) float when something tiny (pebble) sinks? Here’s the reason!
The battle ship is less dense than a rock! Although the ship has more mass than a pebble is is shaped so that it has much more volume. an object that is less dense than it’s surrounding will float, that means if I took a big breath while I was swimming, I would float. But if I was swimming in rubbing alcohol I would sink, why? Because rubbing alchohol is much more dense than water.
Did you know that water is the only known substance that is less dense when a solid! God designed it so that when water froze, it would float on the surface of the liquid water. Otherwise the whole lake would freeze and all life would be extinguished! Our Creator is amazing!
