You learn something new every day.

Between today and last Monday I have learned more about blood splatters than I ever thought I needed to know. The science behind it is actually pretty interesting. For instance, did you know that you can get a good idea of what was used to commit a murder by the size of the droplets in the splatter? Apparently smaller droplets are the result of higher velocity impact (i.e. a gunshot) and larger droplets would result from a lower velocity impact (i.e. a baseball bat).
