I am pretty sure I did the angles in the wrong order 15 degrees is supposed to be the 75 degrees I think. Si I am going to answer this as the 15 degrees is the 75 degrees and the 75 degrees is the 15 degrees.
~As the angle increased, the drop elongated. The drop was more of an oval than a circle.

~As I increased my walking speed, the more the drops splattered. They weren't just a dot anymore, but were spread out.
~The spine became elongated and not as round the faster I walked.
~The distance of my experiment seemed odd to me. The dots I thought were supposed to get farther apart the faster I walked, but the didn't. In my experiment it also dealt with the grip on the food coloring bottle too.

~When one drop landed on another, the spine increased and it spattered out a little bit. The spine almost fills the whole splatter now with only a little rim from all heights.
~The parent drop's diameter increases the higher the drop fell from.
~The satellite spatter increased the more the height increased. On the drops from 40 cm has a spot out above it, and the drops from 60 cm are all right around the drops, but have more outward ways.

~The diameter got bigger the farther up the drop was from. Except for the bottom left one from 25 cm, because more than one drop fell onto that spot.
~You can tell the drops were from straight above because the center of the dots are much darker. As the height increased though, so did the outside part of the spatter that was not as dark as the spine.
