Swing the paddles to the beat of the drum in this classic game featuring Cadaco's patented boom technology. When the ball strikes the paddle a "boom" sound is emitted. Fun for the backyard, great at the beach, what a workout! Add more fun to your outdoor gatherings with Boom Ball Sling Shot. Pull back and release the tethered foam striker ball, for a resounding BOOM! and safely send the foam shot toward your target. The Boom Ball Slingshot is an exciting new way to Slingshot! Includes two shot balls and both the paddle set and slingshot.
