CorelDRAW Graphics Suite X6 :: Making Illustration Of Moving Particle Hitting Other At Rest

My question is maybe more of a creative one than a technical one. I want to make an illustration showing that a moving particle has hit a target particle at rest resulting in a collision, where three new particles have been created. They are moving away from the collision point with high velocity. I have been giving it a try, as shown below, but I am not entirely satisfied, especially not with the two particles from the past creating the collision.

They are both gone after collision, but three new particles have been created after collision - Particle Physics is weird! How to make a nice informative illustration. At the moment I am using transparency to show the fact that the particles are moving ...Maybe I will need two illustrations to cope with the past and the future?
