[Solved]How do I get a cannonball splash effect?

This sounds easy, but for me I've been hitting my head against it for over two days. Anyway, I'll keep it simple. Two objects: cannonball with particle effect, ocean with script to trigger splash and to destroy splash and cannonball x seconds after they hit the water.

My idea is this: Cannonball hits ocean, ocean fires particles, ocean grabs particles as a child (so particles stay right where they hit), then oceans destroys ball and emitter after x seconds (cannonball earlier, particles later).

Problem: Took a bit but here is the issue. The particle system doesn't fire. What am I overlooking?

 using UnityEngine;
 using System.Collections;
 
 public class CannonballEater : MonoBehaviour {
 
     ParticleSystem mySplash;
     
 
     private void OnTriggerEnter(Collider other)
     {
        
         
         mySplash = other.GetComponentInChildren<ParticleSystem>();
         mySplash.Play();
         mySplash.transform.parent = this.transform;
         if (other.tag=="Cannonball")
             Destroy(other.gameObject);
         Destroy(mySplash.gameObject, 5f);
        
                 
     }
 }
