ParticleSystem at when the object hits the ground

Questions & Answers

I managed to destroy the game object once it hits the ground after 1.2 seconds, but I can’t start a ParticleSystem at the position of the impact;

#pragma strict
var removeTime: float = 0.2;
var c : int = 0;
public var DestructionEffects : ParticleSystem; 

    function OnCollisionEnter (col : Collision) {
        if(col.gameObject.tag == "Ground"){
            c++;
            print("Hit"+c);

            var effect : ParticleSystem  = Instantiate( DestructionEffects, transform.position, Quaternion.identity ) as ParticleSystem;
            //Instantiate (DestructionEffects, transform.position, Quaternion.identity ) as ParticleSystem;
            Destroy (gameObject,1.2f);
        }
    }

if(col.gameObject.tag == “Ground” || col.gameObject.tag == “terrain”){

var effect : ParticleSystem  = Instantiate( DestructionEffects, transform.position, Quaternion.identity ) as ParticleSystem;
//Instantiate (DestructionEffects, transform.position, Quaternion.identity ) as ParticleSystem;
Destroy (gameObject);
}
