Why ships foat

 Have you tried dropping a steel bolt in a bucket of water ? If no, so here is what happens. The moment the bolt hits the surface of the water, it begins to sink. Well then in that case how do steel ships that are far larger than a little bolt stay afloat on the sea? This depends on the density on the object in the water. should the density of the object be more than that of water, it is bound to sink. However if the density of the object be lesser than that of water, the object will stay afloat. in the case of  a ship, the density of the vessel is lesser than the density of the water. while the opposite is true in the case of a bolt. Now you know the secret of the sinking  bolt and floating ship.
