Funny, i had been planning to do an Instructable on this, i just haven't had any spare time lately... Just FYI, there are a few different models out there from a few different companies... they all function the same, they're just assembled somewhat differently. i used one from Harbor Freight ($3.99 on sale! w00t!), which disassembled with a couple of tiny Phillips-head screws, at which point you just cut the leads from the body to the wiring grid, then lift off the grid- no glued joints the break or cut. Very convenient. These are high voltage, miniscule current devices- basically, a pair of 1.5v household batteries (AA to C, depending on source), run through a capacitor to up the voltage. The odds of causing cardiac arrest or similar by using one of these as a toy is essentially nil. However, when i did mine i cut the wires to points to increase the sting, and they will actually leave little burn spots in the skin on fresh batteries... looks a bit like a rash, not unlike the results of being kneaded by a cat who refuses to have her claws clipped. Using larger electrodes (soldering the output wires to a pair of brass screws, for example) will reduce this, and give a "deeper" jolt. It's easy to experiment with electrode size and spacing to find a result you like. ...dave
