I don't think any metal will float on water, so some lateral thinking is required here. Mercury is a metal, but it is a liquid at room temperature, and its density is 13.5 kilograms per cubic decimetre (kg dm-3). Compare that with 1.0 kg dm-3 for water, or 7.9 kg dm-3 for iron.
Since the solid iron is less dense than the liquid mercury, this means that iron cannonballs will float in mercury, and this is an example of metal floating in a liquid. See the YouTube video for a demonstration.

No, it is simply just a piece of rock floating in space. The rock is composed of metal and other things that might be floating in space. Hope this helped. Good luck!
