Fill a five gallon pail half full of water, cover the surface of the water w/ sunflower seeds, prop a board up against the pail edge as a ramp, put some seeds on the ramp. I like to think of it as teaching chipmunks to swim; alas, none have passed the course to date. This will do the deal for chipmunks; gophers and 'coons - yer on yer own.
