A large red inflatable ball that was part of an art exhibit at a museum in Toledo, Ohio was blown away by the wind recently. This saw the 4.6m diameter inflatable bouncing down the road and over several vehicles, with attendants from the museum in hot pursuit. They finally managed to halt the 113kg inflatable before it caused any damage or further traffic disturbances. The ball was itself damaged in the incident however and had to be repaired.
