There are many variables to be considered when doing this experment. You have to take into consideration: the height of which the object is being dropped from, the size of the object, the mass and density of the object, the object you are using, and much more.
You need to consider the height from which the object is being dropped from because obviously an object that is being dropped from only a few feet will have a much smaller splatter size and impact force then the object that is dropped from a much higher altitued.
