How to get a ball to go up at random angles?

I'm trying to make a simple ball game where the player has to keep tapping or clicking on a ball to avoid it hitting the ground. I've got it so the ball goes up when clicked but I want it to go up when clicked more like a ball would go up in real life rather than in a straight line up so the player can't just keep clicking in same place to keep scoring.

This is my script so far

Code (CSharp):

1. public class Ball : MonoBehaviour
2. {
3.     public Rigidbody RB;
4.     private float maxTorque = 10;
5.     private float zBounds = 0;
6.     private float xBounds = 7;
7.  
8.     // Start is called before the first frame update
9.     void Start()
10.     {
11.        
12.     }
13.  
14.     // Update is called once per frame
15.     void Update()
16.     {
17.         if(transform.position.z < zBounds)
18.         {
19.             transform.position = new Vector3(transform.position.x, transform.position.y, zBounds);
20.         }
21.         if (transform.position.x < -xBounds)
22.         {
23.             transform.position = new Vector3(-xBounds, transform.position.y, transform.position.z);
24.         }
25.         if (transform.position.x > xBounds)
26.         {
27.             transform.position = new Vector3(xBounds, transform.position.y, transform.position.z);
28.         }
29.     }
30.  
31.     private void OnMouseDown()
32.     {
33.         RB.AddForce(Vector3.up * 10, ForceMode.Impulse);
34.         RB.AddTorque(Random.Range(-maxTorque, maxTorque), Random.Range(-maxTorque, maxTorque), 0, ForceMode.Impulse);
35.        
36.     }
37. }
38.  

 

Instead of just adding Vextor3.Up force, change It to new Vector3(1,Random.Range(-1,1)).

On phone so not sure if syntax is right.
