Does a feather float or sink?
The density of the feather is less as compared to that of water makes the feather floats on water. A light substance whose density is less as compared to that of water floats in water. This is why it is seen that lighter things cannot easily sink in the water rather it floats on the water.
Which is more dense a drop of water or a ping pong ball?
Boats float despite their heaviness due to the large amount of air inside the hull. Hollow objects such as ping pong balls or empty plastic bottles float better than solid objects like baseballs or filled water bottles due to the air inside-air is lighter than water (in a liquid or solid state).
