Cober Valley Rotary Club has been having a ball over the last few months — selling entries into its charity event this Sunday.

The club is holding its annual Ball Splash, this year in aid of Cornwall Air Ambulance, in Coronation Park from 11am on Sunday More than 1,000 balls have been sold. Each ball is numbered and at 2pm on Sunday they will all be dropped into the River Cober at St John's in Helston.
