Pumice is a type of volcanic stone that has a lot of trapped air or gas, and floats. However, most of the lighter pieces tend to be very small.
The explanations I'm seeing is that the stones in the region were actually made from a form of coral. It wasn't clear how they had been dried out, but presumably they would be naturally occurring in the area.
Archeological excavations are apparently finding these coral stones in lower layers under the bridge as if they were placed there.
The stone is heavier than the same volume of water. In short the density of the stone is more than the water. So the stone does not float on the water.
Almost every type of wood will float. There are a few very dense and rare woods found in the tropics that will not float. And if formed properly, pretty much anything can be made to float including stone and concrete.
The stone is broken.
There are two ways:Hollow out the stone to the form of a boat so that has more displacement then weight.Use pumice, a light weight volcanic stone that has lots of air bubbles in its structure.
First, the stone sinks because of the weight, the wood would probably be much lighter than the stone.Second, the density. The stone is much more dense than the wood
No. Only pumice (volcanic) stone can float.
A stone that can float on water is a pumice stone. Ejected from a volcano, and full of holes, it has been known to float.
