I'm doing an experiment on a penny: How many drops of water can a penny hold?
The question I'm askin' Yahoo! is...
Does the side of a penny affect how much drops of water it can hold? (as in if it's heads...you get like 60 drops...but if its tails, you can only get like 49)

The side of the penny has nothing to do with how many drops it can hold. It is the ability of water on the surface of the penny to hold each other before it breaks. It's called "surface tension".

Well, the tails side of a penny would have the indents more that the heads side would, and at a 10th of a centimiter apart, I would say the tails side of the penny would hold more drops then heads, however very few, if even one. Depends on how far away your dropping the water from and how much is going onto the penny at a time...

It would just be my guess, but not only would the side of the penny affect this experiment, but so would the wear on a penny. If I were to guess, a freshly minted penny would have a more definable rim and would hold more water than a well-worn penny. But all in all, the differences would probably be fairly negligible.
Interesting experiment.

The side you test could affect the result to some extent, depending on how high the relief of the head and the memorial are. How clean the penny is will also make a difference. Pennies of designs other than the current one can also vary.

Hello, i did that science project in my school, too. It was about 2 years ago but i remember that soapy water, and salty water had a different effect on how the water stood on the penny. We used eyedroppers, but i think that the sides do matter a little bit. But to get a 'ballpark' idea, try it alot of times to get a average # of drops, on both sides. Otherwise you would never know. Goodluck, and if you can ask your teacher. :)

Since the designs and the surface areas are different, i would assume one side will hold more water than the other.

I'm not sure why you can't determine this for yourself.
An eyedropper, a penny, a few minutes of patience.
This is really too easy an assignment for you to ask for help with.
Get with it kiddo!

surface tension. water actaully "sticks" to itself which prevents it from going over the sides. the sides do play a part in it. try it with different water like soapy water or salt water and see what happens
