iOS touch triggers the wrong object

Hello. Can someone tell me what I'm doing wrong? I have several objects in a scene, and I want to be able to tap them to to manipulate them in different ways. Some of the objects are fine, I tap them and they animate/whatever. But when I tap some other objects, an animation in a completely different object occurs. I feel like I'm missing something simple here and I think I've come across this question here before but I can't find it now.

Please help me :)

EDIT: this is the code in the js-script attached to the object I tap and want to animate:

  function Update () {
 
 }
 
 function FixedUpdate() {
 for(var touch : Touch in Input.touches) 
 {
     var ray : Ray = Camera.main.ScreenPointToRay(touch.position);
     
     if(touch.phase == TouchPhase.Ended) 
     {
         
         var hit : RaycastHit;
         
         if (Physics.Raycast (ray, hit, 100.0)) {
         //Debug.Log("Touched...");
         //var curX = Input.GetTouch(0).position.x;
         //var curY = Input.GetTouch(0).position.y;
         //Pos = Instantiate(curX, curY, 1000); 
         //Pos.rigidbody.AddForce(transform.forward * speed);
         rigidbody.AddForce(0, 1200, 0);
     }
 }
 }
 }

And this is the code in the cs-script attached to the object playing its animation:

     public class TouchBlueTeapot : MonoBehaviour {
     
     public Animation m_animation;
     
     // Use this for initialization
     void Start () {
         Debug.Log("started");
     }
     
     // Update is called once per frame
     void Update () {
     foreach (Touch touch in Input.touches)
             
 {
     Ray ray = Camera.main.ScreenPointToRay(touch.position);
             Debug.Log("RAY:" + ray.direction);
     
     if (touch.phase == TouchPhase.Began)
     {
         Debug.Log("touchphase position:" + touch.position);
         RaycastHit hit = new RaycastHit();
         
                 
         if (Physics.Raycast(ray, out hit, 1000))
         {
 
             
             Debug.Log("touched " + hit.transform.name);
     
             
                     gameObject.animation.Play();
                     
         }
     }
 }
     
     
     }
 }

Sorry if it looks kind of crappy...
