The ones which float have a lower density than water, whereas those which sink have a higher density than water. However, also the shape the material is in influences whether it sinks or floats.
material that sink has a density above that of water and does not obey the law of floatation.
Well it depends on what the 'different' items are.
rocks metal eggs dirt or sand all sink some woods sponge plastic aluminum cans all float
Boats can sink. They are usually made of materials that allow them to displace water, and permit them to float. From time to time, that material will break down, and the boat will sink.
