The water bubbles up because of cohesion.
Cohesion: the force of attraction that holds together a substance's molecules; cohesion is strongest in solids, weaker in liquids, and weakest in gases.
The water doesn't spread out evenly all over the penny because the H2O molecules are so strongly attracted to each other (opposites attract, so yeah, hydrogen is pos. and oxygen is neg, so one H2O molecule is attracted to another one, either through the hydrogen molecules or the oxygen molecules) that it forms a bead because they're all grouping up together.

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.
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.
What keeps water on a penny?
Surface tension keeps water on a penny even when it goes over the surface of the penny and you think it would spill over the edge due to gravity. I believe surface density is accomplished due to the fact that the hydrogen bonds, for that scale, is stronger than the force of gravity. For more information look at the Related Links below.
What are the results of can water float on water?
Yes, water can float on water. This is because of surface tension, which allows objects with a lower density than water to float on its surface. Items like boats or water bugs can float because of this phenomenon.
Will a styrofoam cup float or sink in water?
A styrofoam cup will float in water because styrofoam is less dense than water, causing it to displace water and float.
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.
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
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.
Why will a penny float in cooking oil?
it will float bc the penny is so light that it should 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.
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.
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.
Why does a penny sink in water?
water has a density of 1. For something to float, the density of the object would have to be under 1, and to sink, it must be over 1. If it is exactly 1, then the object will remain suspended in the water. A penny has a density of over 1, so it sinks in water.
How does an air craft carrier float in fresh water when a penny sinks in fresh water?
aboat floats because it displaces it,s weight in water when that happens it stops sinking a penny cannot displace it,s weight in water so it sinks hope you understand
