Catching worms with electricity

I have been using this method for a few years now. It does not give you high quantity's of worms, but you will not get dirty. It is perfect for when you go fishing or feeding a few pet frogs.

All you need to do is put metal electrodes in the ground an run some AC current through it. The worms start surfacing within a minute. You can just pick them up. I think it has something to do with the pulsating current, this probably simulates a heavy rainstorm. Or it just gives them a lot of pain and they flee to wherever there is no current.

You have to be careful that you are not part of the circuit. You can separate the circuits by using an isolation transformer or a generator of other portable power source. Never use the AC grid directly! 230V AC seems to work pretty well with an electrode distance of about 40cm. The current stays below a few amps, depending on the moisture and minerals. You can try using different distances with different voltages. I use a 12V battery and a 1kW 230VAC inverter.

I had some old high voltage switchgear laying around, and decided that these would make perfect electrode handles. I attached 50cm of M6 Stainless steel threads as electrode.

Originally I saw this idea being used in the movie Godzilla, where one of the scientists was examining worms in a radioactive area. He used a generator in the back of his truck. I decided to try if this works in real life and it did!
