The penny because it has more pressure.
A hammer falls faster than a feather when dropped on Earth because of gravity. Gravity pulls objects with mass towards the Earth at a constant rate of acceleration, regardless of their size or shape. Since the feather has more surface area and air resistance, it falls slower than the hammer, which is more dense and streamlined.
When you drop a feather, the two main forces that will affect it are gravity, which pulls the feather downward towards the ground, and air resistance, which pushes against the feather as it falls, slowing its descent.
The hypothesis of the penny drop experiment is that the design of the container, the height from which the penny is dropped, and the amount of water in the container will affect whether the penny lands heads up or heads down.
In a vacuum, a feather and a quarter would fall at the same rate due to gravity's influence. However, in normal conditions with air resistance, the feather falls slower since it has a larger surface area, creating more air resistance.
fall at different rates due to differences in their mass, size, and air resistance. The penny will fall faster because it has more mass and therefore experiences a greater force due to gravity. The feather, on the other hand, will fall slower due to its larger surface area and greater air resistance.
If there was no air resistance and a feather and a penny were dropped from the same height they would both pick up speed by the same amount and they would hit the ground at the same speed and at the same time.

They all drop at the same rate. Only objects that are fuzzy in some way drop slower because air resistance slows them a little. If there were no air, a feather and a cannon ball would drop at the exact same rate.

a penny
Purely air resistance, the feather floats on the air. The mass is irrelevant. If a penny was dropped at the same time as a brick (ignoring wind resistance) both would hit the ground at the same time. Look up Galileo's tower of Pisa experiment. http://en.wikipedia.org/wiki/Galileo%27s_Leaning_Tower_of_Pisa_experiment This also includes a video of a feather and a hammer being dropped on the moon (where there is no air). Both hit the ground together.

Light
A rock falls faster than a feather due to differences in their mass and air resistance. Air resistance affects the feather more than the rock due to its larger surface area and lighter mass, causing the feather to fall more slowly.
