Particle trail follow object

Questions & Answers
1

I was wondering if the following was possible. I'm working on a 2d top down game where I have derby fly off the screen with a particle trail. At the moment I have this setup by parenting the particle effect to the derby object. My problem with this is, I'm trying to destroy the object when it leaves the screen. When I do this the particle trail disappears. Is there a way to get the particle trail to hang around until it disappears?

I can think of two options:

1 - let the object go a little further as to get the particles of screen as well

2 - detach the particles and destroy them after say 5sec

This piece of code from the help docs should get you going:

transform.DetachChildren();
Destroy(gameObject);
