How can a penny float?
A penny will not float in water, mainly because it is denser than water. When the penny is placed in water, it displaces a volume of water equal to its own volume. Since the penny weighs more than the water it displaces, it will sink.So, in order for the penny to float, you must find a liquid that is denser than solid copper -- or whatever metal or alloy a penny is made of. Mercury -- which is a liquid at room temperature -- is denser than copper. Hence, a penny will float in mercury.Possibly surface tension may allow it to float.
