Hi Derek, Yes, you are right. The higher the level from which you spill the water, the greater will be the area of the splatter. This is because when you raise any object you spend your energy, which is converted into potential energy. Potential energy is the energy that is stored in a body due to its height. The higher you raise an object, the more will be the potential energy stored in it. When you drop that object (the object is a liquid (ie: water) in your case, this potential energy gets converted into kinetic energy, which is essentially velocity. What this means is that if the object is raised higher, it will gain more velocity (speed in simpler terms) when it hits the ground. When it hits the ground, the ground does not allow it to go any further down and hence the droplet has to move away. Thus it moves in a direction away from the centre (and hence the splatter all around the point at which it drops). Since it has a higher kinetic energy it to moves further away from the centre before coming to rest on the ground. Hope that helps. In case you need any further clarifications, feel free to contact us again. Bye, Nauzad
