Adafruit Industries Adafruit Industries Copper Foil Tape with Conductive Adhesive - 6mm x 5m Long
Copper tape can be an interesting addition to your toolbox. The tape itself is made of thin pure copper so it's extremely flexible and can take on nearly any shape. You can solder to it, and the tape itself can carry current just like a wire. On the back is an electrically conductive adhesive. The adhesive can't carry significant current, but it is very handy for sensing applications where you don't want to solder the copper tape.
