I want to make a table fall over when the player touches it, how do I do that?

I have tried messing with a rigidbody but it only falls over if you jump at it. I need it to fall over when you touch it so a bowl can fall to the ground. How can I make that happen?

you could try to experiment by adding y force equal to the x/z force.

try adding some y force on collision -

 //always cache Components if you're going to use them more than once
 private RigidBody rbody;

 void Start () {
      rbody = gameObject.GetComponent<RigidBody>();
 }

 void OnTriggerEnter (Collider other) {
      if (other.gameObject.tag == "Player") {
           rbody.AddForce (new Vector3 (0, 100, 0));
      }
 }

see if that works
