A water-filled ping pong ball collides with a water balloon at approximately 25 m/s. The inelastic collision dramatically deforms the water balloon. The ping pong ball weighs 0.033 kg and is propelled by a Toro leaf blower; the water balloon is 3.36 kg and is suspended by a single string. The airflow from the leaf blower acts to slow down the rebound of the ball. Shot in 600 fps. Special thanks to Rob for letting us use the camera and setup.
