Does milk float on water

Answer 1

No, they will mix together to give watery milk. Yummy!

Answer 2

A fresh egg will sink in water, but less decisively as time goes on, and will begin

to float by the time it's a week or two old.

The density of most eggs is just slightly more than the density of water. Most

will float in salt water or milk.

Answer 3

Things float when they displace less water, in weight, than their own weight.

If we're not thinking about boats, we can view it this way: things float when they have a lower density than water. Water has a density of 1.000 g ml-1.

So what's the density of milk? Well...it depends on the type of milk. High fat milk might be a little less dense than full skimmed milk.

Well a quick search gives a pretty handy table of such things:

So apparently most types of milk will in fact sink in water. Heavy cream will float. A packet of light cream will likely float but only by virtue of any air trapped in the packet.

Milk essentially is a colloidal mixture of water and fat. It has many minerals dissolved into it and so makes sense that it is generally a little more dense than water is.

This reminds me of a small experiment used to demonstrate density to children, whereby a can of coca cola will sink but a can of diet coca cola will float. This is because the sugar solubilised in the regular coca cola bumps the solution's density over 1g ml-1 and thus makes it sink (material dissolved into solution will add to the solution's mass (or weight) but does not effect its volume).

Answer 4

A whole fresh egg including the shell will float in milk.

Answer 5

Yes, milk is less dense than water, so it will float on top of water.
