create a small gun to shock your friends, family, or pit bull. (I highly discourage that last one.) and also, it's my first instructable.
Step 1: Get Parts
the parts you need are simple:
ac adapter (old toys, electronics, etc.)
battery (9 volt)
wire (doesn't matter what kind, I used telephone wire. but if you want it to hurt more, then you could use a wire with multiple wires in it because it would go across the battery more.)
Step 2: Take Apart Adapter
as the title says, take apart the adapter. you don't want to clip the wires coming from it, in case there's not enough wire actually inside the adapter. also, obviously, don't do this while it's plugged in. I don't want to get sued.
Step 3: Attaching Battery
first, put one end of the wire from the adapter on the battery terminal. then, attach more wire to the other wire, so that you have a longer wire.
Step 4: Tape It Together
well, just tape it together however you want. I taped the battery to the back of the adapter just to put it easily within reach.
Step 5: SHOCK PEEPS!!!!
now go around and shock people. but I warn two things: this hurts, so do it to yourself first, and also, don't shock people anywhere that they might, like, have a seizure or something. and I guess don't shock people who get seizures either. and people also tend to get mad. be prepared to run away.
you could experiment with capacitors, or maybe actually turning it into a gun (ie, adding longer wires, propellant, etc.). you could also maybe try putting another adapter on top of the first one and step it up even more!
don't sue me if you do something with it and get hurt. I don't mean for anyone to get hurt, as this is purely educational. (right.) so yeah.
