Do you want to take over the world? or just annoy your roommate? This should probably do the trick (to annoy someone, taking over the world is a little far fetched)
Step 1: Materials
For This Instructable you need:
* a piece of tin foil (or other conductive materials)
* electrical wire
* Polyurethane sponge (with scouring pad)
* a knife (i used my scalpel) or scissors

Step 2: Rip It Apart

Cut it in two and cut a round hole in the middle.

Strip the end of a piece of wire and fan it out,
Tape this to a piece of tin foil and fold it to the size of the scouring pad.
Repeat this step
