Worm charming; pick a likely spot, stick a fork in, and rhythmically
rock it backwards and forwards rapidly ( not actually digging up any
soil ). Up the worms will come. I believe a similar effect can be had
stamping or pummelling the ground. Harder work than the rain and
plastic sheet method but more fascinating.

Does this really work?

And what kind of ground should I pick?

Am I really going to look a prat for half an hour?! B-)
