Game Object Deleting Itself Prematurely

I am working through the Unity tutorials, and am currently on a tutorial called "Space Shooter." Something fishy has happened.

I noticed that the Boundary object, and the asteroid object both disappear when the game begins running. Note, both have colliders, and they are not touching. Their is a script called "DestroyByContact", which essentially destroys the game object whenever the player shoots it. 

using UnityEngine;
using System.Collections; 

public class DestroyByBoundary : MonoBehaviour 
{ 
     void OnTriggerEnter(Collider other) 
     { 
           if (other.tag == "Boundary") 
           { 
                return; 
           } 

           Destroy(other.gameObject); 
           Destroy(gameObject); 
     } 
}

I found that when I delete this script off of my Asteroid gameObject, the game functions normally, and the objects are deleted. Their must be something wrong with the script, but I cannot find out what went wrong.

EDIT: I forgot to place the Boundary object to the tag "Boundary" in Unity. This fixes the problem.

Most likely you have not set or misspelled your boundary's tag Boundary1. See This point in the tutorial video.

This is causing your if (other.tag == "Boundary") to be false so it does not go in to the if block to exit the function early.

P.S.: If you are using Unity 5 you should now use if (other.CompareTag("Boundary")), it was not in Unity 4 when the space shooter tutorial was written and it supposedly has better performance than doing a other.tag == "Boundary" compare. You can see a example of it used in the Roll-A-Ball tutorial which is written in Unity 5. The Roll-A-Ball tutorial also has a example of adding a new custom tag in the Unity 5 UI.

1: Ironically I misspelled Boundary when I first posted this answer.
