The scenario involves dropping something into a bucket of water. I'm trying to do an experiment where I have to figure out a relationship between the amount of water that leaves the bucket and a certain variable of the object that is dropped. I'm wondering what could maximize the water that leaves the bucket. The waterlevel will be 4 cm below the height of the bucket. The object will be dropped 1 meter above the water level. To keep things simple, nothing that involves any moving parts/suction/nuclear/electrical interactions. I'd like to know what kind of variables are involved in calculating the amount of water that can be splashed out of the bucket and how to maximize them.
