How to Make a Soft Tip Stylus for the iTouch

Test your kitchen sponge by brushing it across the iPod touch's screen to make sure it can be detected by the device. Organic sponges typically perform the best, but you may need to experiment with different types and brands to find one that the iPod touch can detect.
Cut a rectangular piece of sponge approximately 1 inch by 2 inches. The depth is determined by the depth of the kitchen sponge, but is ideally around 1 inch.
Squash the sponge and roll it into a tight cylindrical shape 1 inch long.
Wrap the thin copper wire around half of the sponge to help it keep its cylindrical shape. Leave at least 6 inches of copper wire free.
Twist or unscrew the artist's charcoal holder to open it wide enough to slide the copper-bound side of the sponge cylinder into it. Tighten the holder to grip the sponge, leaving approximately one-quarter of an inch of sponge protruding from the holder. The free piece of wire should also protrude from the end of the holder.
Wind the remaining length of wire around the holder. Keep the wire tight, though the spiral can be quite wide. Secure the wire at the opposite end of the holder to the sponge using a piece of sticky tape. The stylus is now ready for use on your iPod touch.

How to Get a Nintendo DS Stylus to Work on an iPod Touch

Cut a length of sponge roughly half the length of the DS stylus and about four times as thick with your scissors.
Penetrate the length of sponge with the stylus, almost like sliding on a pen cap. You may need to cut a small hole at one end of the sponge if the stylus cannot penetrate the sponge on its own. Insert the stylus as far as you can, since you need to end of the sponge to be as firm as possible.
Leaving about a quarter-inch of sponge protruding from the end of the tape, secure the rest of the sponge to the stylus with a generous wrapping of adhesive tape. Wrap the tape around several times to create a secure hold.
Wet the protruding edge of the sponge with plain water. When wet, the sponge is capable of conducting electricity and will respond nicely to a capacitive touchscreen. Your DS stylus has now been modified to work on your iPod Touch.
