Fire a Projectile towards a specific object?

I’m making a 2D Side Scroller and I’m trying to launch a projectile from an object called “StrawSpawn” towards and object called “Target” at a speed of 20.

With my current code my projectile always fires off to screen right at a slight angle and nearly too fast to see, regardless of where “StrawSpawn” and “Target” are located relative to each other.

Can someone take a look at my code and tell me what I’m doing wrong? Thanks.

var projectile : Rigidbody;
var speed = 20;

function Update () 
{
    // Put this in your update function
    if (Input.GetButtonDown("Fire")) {

    // Instantiate the projectile at the position and rotation of this transform
    var clone : Rigidbody;
    clone = Instantiate(projectile, GameObject.Find("StrawSpawn").transform.position, transform.rotation);

	clone.velocity = transform.TransformDirection (GameObject.Find("Target").transform.position * speed);

	Destroy (clone.gameObject, 3);
    }
}

After asking on the forums, this is the working code I ended up with for anyone else looking to do something similar:

var projectile : Rigidbody;
var speed = 20;

function Update () 
{
    // Put this in your update function
    if (Input.GetButtonDown("Fire")) {

    // Instantiate the projectile at the position and rotation of this transform
    var clone : Rigidbody;
    clone = Instantiate(projectile, GameObject.Find("StrawSpawn").transform.position, transform.rotation);

	clone.velocity = (GameObject.Find("Target").transform.position - transform.position).normalized * speed; 
	clone.velocity.y=0;

	Destroy (clone.gameObject, 3);
    }
}
