I can make a iron nail float. Simply melt some lead and the iron will float on top of the lead. Your question seems to be with regard to how do Boats float and the answer is Bouyancy. The Boat displaces a volume of water and if the weight of the displaced water is less than the weight of the boat, the boat will float.
If the proposal is to float the metal on water, most metals won't float. That's because most metals are more dense than water and will sink. Note that this proposition sets aside any reaction that might occur between the metal and water. This is because there are some metals that react with water, and some react violently. See the link below to the related question about the metals that will float on water. There aren't many of them. If the metal you are considering isn't on the list of metals that willfloat on water, then it won't.
If the can is empty, and you avoid water from entering it, it will float without any trouble.
If the object, when submerged in water, displaces a volume of water whose mass is greater than its own, then it will float. The density of the material from which it is made is not the key as can be seen from the fact that ships made of metal will float.
You do not. A metal ship, with density well above that of water, will float.
if you place a flat piece of metal on water will it sink or float
You can't make a bar of metal float on water, but boats with metal hulls float. Also, metal bars and other metal objects float on mercury.
For something to float, it must displace the same amount of water as it weighs. Answer:To float in water, a solid metal object must be lighter than the water equivalent to its volume. This would make lithium (at S.G. 0.53) the only metal that would float in water.Objects which are hollow and made of metal float because the contained volume of the object divided by the weight of the object is less than 1 gm/cm3, the density of water. Solid metal objects can float in liquids which have a density greater than they exhbit thesmelves. As an example, almost all metals will float in mercury

Metal ships are built to float.
if u made the piece ofmetal hollow it can float unless its density is larger than the water densityANSWER:If you make it displace more water than what makes it sink, it will float, as in a ships hull. If you make pontoons out of it, it will float. If you make an enclosed shape that contains enough air, it will float. There should be less density in the item than the water.
No, for a sword is made of metal and metal is heavier than water.

You must displace as much water at the metal weighs. So there is equillibrium between the metal and the water.
Paperclips sink in water because they have a higher density. Unlike wood, a paperclip will sink not float.
If the object does not quite float in water, adding salt to the water might make the object float, yes.
Common metal earring don't float in water. However, you could design on that float by make it hollow. Jewellery design is unlimited, long as it can hung beautifully then anything could be possible, even using plastic to make an earring. I would think the back of the earring could be light and flat enough to be supported by the surface tention of water.
It displaces water and is filled with air.
