No; gold, aluminum and steel are all denser than water and a solid mass of any of these three metals would sink (unless their shapes were hollow and could thus displace more weight in water than their own mass). Lithium metal, which is less dense than water, can float on water (although, of course, it would be highly reactive).
A material needs a lower density than water to float in water. Ships float in water because their average density is lower than water. The average density includes the steel hull and the air inside the hull.
Aluminum has a density of 2.7g/cc which is higher than that of water (1.0g/cc) and ordinarily would sink; if the can was empty and thus (like a boat) able to displace more weight in water (by virtue of its volume) than its own weight, it could then float. However, if it was filled with water, its overall density considering both the metal and the container's content, would be higher than water, and it would sink.
There are tents designed to Float in water. But not all tents designed to float.
Soil floats on water!
It's the balloon's volume and mass. If a thing has enough volume to compensate for its mass it will float on water, which also explains why steel ships can float, they have a huge hull. Check out the Yamato, a huge battleship of Japan during WWII.
I think it can float on water.
it is hollow so it will float
No it is to heavy
yes, it does
No. Bicycles are mostly made of steel, which does not float.
Steel don't float on water because the density of steel is greater than the density of water.
The density is not directly relevant. Otherwise, ship made of steel would not float on water.

A fork can float if it is made of the right material. A fork that is made from stainless steel will not float in water, but a fork made of plastic will.
Not as long as it's still in the shape of a block. But if you re-shape it into the shape of a cup ... whether round or rectangular ... it will float, because it displaces much more water than a block does. If your cup-shape is done artistically and with care, people may call it what it looks like ... a little "boat" or "ship". Those objects are usually made out of re-shaped blocks of steel.
The ship has enough gas in it to keep it afloat.
Because, your body weight is to heavy for steel to Carrie on water, and they will role away.
