How do I Bounce upon Collission?

I just want a random angle bounce upon Sprite hitting Solid. How would I do that?

Clarification: I want to spawn an object and have it drop and hit something. Upon hitting it I want it to bounce.

You can use the bullet behavior with gravity and on collisions with solid set angle of motion to random desired angle.

If there is lots of bouncing etc, you might look into the physics behavior, but that has the potential to add lots of additional complexity.
