Stickiness Stickiness controls how much particles are inclined to cling to the surface of the collision object.
A max value of 10 will make the particles slide along the surface of the object without bouncing at all.
Kill Particles Kill Particles causes particles to die on contact with the collision object when the option is
checked, regardless of what their life span is set to. By default, particles disappear on death, but they can be
set to be visible after death in the Render section of the Visualization tab.

deflection object with a Damping Factor value of 0.5. If the Damping Factor value is 1, the particles will not
bounce at all.

Damping Random Damping Random adds a random component to the Damping value, so that some
particles are more dampened than others.
Friction Factor Friction Factor reduces the particles' acceleration parallel to the surface of the deflection
object when the particles come into contact with the surface. Figure 6-24 illustrates the difference between
