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.

Why will a penny float in cooking oil?
it will float bc the penny is so light that it should float.
How do you make a penny float?
One way to make a penny float is by using the surface tension of water. Carefully place the penny on the surface of water in a bowl or cup, making sure it is placed flat. The surface tension of the water will allow the penny to stay afloat.
Why does a boat float in salt water but not a penny?
penny's aren't tall enough!
Why doesn't a penny float in the water?
because you're fat
Why will the penny float if you toss it in a wishing well full of a liquid denser than the coin?
no it wuld float on surface......
Can you make a penny float?
No, pennies are too heavy to float on water due to their density. However, you can create the illusion of a floating penny by carefully balancing it on the surface tension of the water.
Does a new penny float in hcl?
when the penny is reacted with HCl, there must be somesort of area where the copper on the outside of the penny is removed so that the HCl can react with the zinc inside because HCl does not react with copper. Once the HCl reacts with the Zn inside, it will dissapear and therefore become less dense then the ZnCl2 that is formed which causes the penny to float
Why would a golf ball float on water and not a penny?
Only special bought golf balls float, and they are designed with air inside. That air obviously is lighter than water and will always rise, a penny however has no air and is stream lined to slide through the water. :D
Can a hockey puck float on water?
No, because a hockey puck has a higher density than water. In some cases, objects with higher density than water can still float on the water, if they are small enough to avoid breaking the surface tension of the water. This is also the case if the object's mass is distributed across a large enough area, so you could float a penny on water if you put it down flat across the water, but it would not float if you dropped it in on its side. You also could not float that penny if you melted it down and made it into a sphere, for example.
Which object has the greatest density a ping-pong ball a penny water or a duck?
Penny. Put the ball, duck and penny in water. Only the penny sinks.
Can a penny float in salt water?
A penny as everyone I'm sure knows cannot float in regular water. As for salt water a penny should in theory not be able to becase the regular pennys bouancy is not great enough to support the weight of the penny regardless of the salt to water ratio. A penny is too dense to be able to float in salt water, regardless of the salinity of the solution.
How much would a penny weigh on the moon?
It is really hard to tell because there isn't any gravity in space so it would just float around.
