 Children strain the mud to look for shrimps and worms |
People in Lancashire are being asked to donate their old tea strainers to an education centre in the Ribble Estuary. Schoolchildren who visit the Ribble Discovery Centre in Lytham St Annes use the strainers to sieve the mud to look for shrimps, worms and snails.
But staff say the rise of the tea bag means strainers are now a rare find.
Centre manager Ruth Fraser said: "It would be a real shame to lose this fun activity simply because of a lack of such basic equipment."
The centre, near Fairhaven Lake, is run by the Royal Society for the Protection of Birds (RSPB) in partnership with United Utilities and Fylde Borough Council.
Mud-dipping is a popular activity with visiting schools, as the children learn about the creatures that live in the mud and why the estuary is important to migrating birds.
