Blood Flight Characteristics:
- Blood will not break up unless it is acted upon by force. The force must be great enough to overcome the surface tension of the blood
- Blood forms a spherical shape (perfect circular shape) almost immediately upon separating from the blood source. The spherical shape is caused by the surface tension of the blood.
- Surface Tension causes the blood drop to pull itself in; both horizontally and vertically.
- The blood drop will settle into a spherical shape, as a result of the surface tension.
- The surface tension will maintain the sphere shape of the blood drop until it impacts with the surface.
