Description
This pattern was generated by placing a source of blood approximately 2 cm from the target and keeping it there to accumulate enough volume.
A pool of blood may be formed if there is enough blood in the source and it is not too far from the target. As the source is raised from the target it more likely will form a drip pattern. However if there is sufficient volume the drip pattern can be obscured and all that remains is the pool of blood.
