Does bone float in water?

Question

I was watching mythbusters and they were trying 2 find a needle in a hay stack. They had 3 metal needles and 1 bone needle and they olny checked if fa metal needle floated but it sunk....... and they did'nt check if a bone neeedle floated or sunk!!!!

Answer 1

It all depends on buoyancy and density.

If the weight of an object is less than the weight of the fluid the object would displace if it was fully submerged, then the object is less dense than the fluid and it floats at a level so it displaces the same weight of fluid as the weight of the object.

If the object has exactly the same density as the liquid, then it will stay still, neither sinking nor floating upwards, just as the liquid nearby stays still.

UNLESS,

An object made of a material of higher density than the fluid, for example a metal object in water, can still float if it has a suitable shape (ex: hollow) that keeps a large enough volume of air below the surface level of the fluid. In that case, for the average density mentioned above, the air is included also, which may reduce this density to less than that of the fluid.

Answer 2

I think it depends on the bone. If it is independent of anything attached to it, and it's old, it might sink due to being so porous and could become filled with water. I'm not sure.

Answer 3

yes!
A bone does float on water.
It is made of a special kind of psytoplasm that is much lighter than water. (u can consider it to be some where between wood and calcium)

Answer 4

if it is in salt water then it will have the chances of not sinking but if it was in plain water it has a big possibility of sinking

Answer 5

yes

Answer 6

i eat bones

Answer 7

It will sink.

Answer 8

I'm guessing...no!

Answer 9

no!
