The Silbaby Archaeo-challenge.
Get all the psychics, dowsers, geofizzers and anyone who has a pole, some rope and a clear head, to each demonstrate their particular method. First team to conclusively prove anything about the age of Silbaby gets a prize.
Possibly a Genuine Neolithic* replica of King Sil (made from plastic).
*as advertised on e-bay, under flints/beads etc.
Nb: I already have my coat on.
