Abstract: A system includes a tubular string and a hollow ball. The tubular string is adapted to be deployed downhole in a well and includes a seat. An activation ball adapted to be deployed in the well to lodge in the seat. The ball includes an outer shell that forms a spherical surface. The outer shell forms an enclosed volume therein, and the outer shell is formed from a metallic material.
