Thread title doesn't give any description of your problem, and your actual question doesn't give any description of your problem. Not a great start but I can just about make out that you might want the bubbles to collide with each other? Look into attaching colliders to your objects and using rigidbodies.
Looks like your colliders are a bit off, don't worry , thats a very easy fix . Just go into the object prefab and find the collider and make it a tad bigger
