How surface tension behaves?
for example, if drops of water are placed on the top of a penny, the surface tension is going to hold the drops on top of the penny. when the penny can hold no more, it will all overflow. make sense?

How many drops can you hold on a penny list one uncontrolled variable?
The penny's state of corrosion.
How many drops of water can a penny hold on its surface?
Water has a surface tension. When dropping water on a penny, people usually underestimate how much water the surface of a penny can hold. The surface tension of water is strong on a smaller surface, and when dropping water on the surface of a penny, towards 20 drops the water on the penny will look like it is bulging out a lot. It really depends, depending on which side of the penny you are using, it ranges from 6 to even 34 drops using a simple eyedropper. Because eyedroppers do not produce the exact same size of drops every time, the result is not very accurate. To be even more accurate, scientists use accurate distributing machines and a very new penny to determine how many drops of water it can hold without vibrations. There could be certain amounts of grime and dirt on a penny, depending on how old it is, which can affect how much water can be put onto it. Different types of water can also change how much a penny can hold. Tap water has certain amounts of chemicals in it, and that could also affect the weight and surface tension of the water on the penny. The height of which the water comes off from matters too, the more force of the water that comes down, the more likely the water on the penny is to splash and spill. The place the water lands on also has an effect on it. To be even more accurate, light has a mass. If light shines directly at the water on a penny, it could push it a tiny bit. This change is impossible to see, and it has basically no effect on the penny or water at all whatsoever. Remember, all tests may not be 100% accurate, and there may always be a chance that there is a better way to make a penny hold more droplets of water than the presumed "most advanced and accurate" way.
Why does a penny hold water?
sit the glass of water on the penny
How many drops of water can fit on a US penny?
One large drop of rain, or as many as 20 average-sized drops of water from an eyedropper, given maximum surface tension. As many as 35 of the smallest drops can hold together atop the coin.
Why does your penny hold so many drops?
it is big inside but small out side
Why does a penny hold so much water?
A penny is a solid, flat object and does not hold much water at all.
What variables may play a factor in the amount of drops the penny hold?
Several factors can come into play here.The size of the dropsHow fast the liquid is being droppedWhat type of liquid is being usedThe temperature of the liquidThe termperature of the pennyIf the penny was clean or dirtyThe height the drop falls fromAny of these things can have an effect an expansion of the liquid, surface tension, and splash.
How does a penny hold water?
by blocking a standard water pipe
How can you compare the surface tension of various liquids?
This year my teacher made us use a transparency and we dropped water, oil, alcohol, and i think it was water with salt ...not so sure... well then we recorded which one stood together and which one separated the fastest.....be sure to illustrate if this is a science fair project. hope i helped if not well sorry i tried: )______________________________________________Another way is to take a penny and for each type of liquid, count the number of drops that the penny can hold before the liquid's surface tension breaks.
