An electric fence to keep snails out of your vegetable garden

Here's a vegetable gardener who didn't want to share his bounty with slugs and snails, so he strung an electric barrier around the perimeter of his raised bed garden. Anytime a voracious mollusk attempts to enter the garden, it must first crawl over a pair of electrified wires, where it receives a mild shock sufficient to thwart its plans.

The gardener has kindly posted instructions for others interested in making a 9 volt electric snail/slug fence.
