How many drops of soapy water fit in a penny?
Ideally, everyone performing the experiment would include the following: - distilled waterThere are a lot of factors involved. The cohesion and adhesion ('stickiness') of water molecules can be effected by things like oils (on surface pennies from peoples' skin) and other contaminates on the penny. The size of the dropper or pipette will determine the size of each water droplet - the larger the drop, the fewer number of drops will fit on the penny. The manner in which the water is added to the penny is also a factor. Water has a cohesive nature (the molecules are kind of like magnets and are attracted to one another). Therefore, if the drop from the pipette is allowed to touch the water already on the surface of the penny, the water can be 'pulled' out of the dropper. When this happens, the size (volume) of the drop is not always the same - it could be a very small amount (which will result in a very large number of drops), or a large amount. Soap causes the cohesiveness ('stickiness') of the water molecules to decrease so they are not as strongly attracted to each other. Because of this, when soap is added to the water the number of drops that can be placed on the penny will decrease. The water molecules can't 'stick' together as well, so the water on top of the penny spills off sooner than it would with non-soapy water. Ideally, everyone performing the experiment would include the following: - distilled water (to start with) - same type/size of calibrated dropper/pipette - same date of penny - penny cleaned as thoroughly as possible using same cleaning procedure - same 'dropping' procedure

Why is the Two Pence coin so large?
When decimal currency was introduced in 1971, the weight of the 2 New Pence coin was set at twice that of the New Penny. Since there is very little difference between the thickness of the coins, in order to meet the weight requirement, the coin has to be significantly broader. Original New Penny coin - Weight: 3.56g (Which was also twice the weight of the Half New Penny). Original 2 New Pence coin - Weight: 7.12g.
What is the control on the penny water drops experiments?
In this experiment, the control group would be the penny! The independent variable is the substance/water on the penny, and the dependent is how many drops the penny takes.

Get on the scale without the penny, take a measurement. Get on the scale with* the penny, take a second measurement. The difference is the weight of the penny. Note - it will be more accurate with a Digital bathroom scale.
