Step 1: Wrap aluminum tape around clothespin tips Wrap aluminum tape around both tips of the clothespin, leaving a tab on each end so you can attach wires. Step 2: Tape electrical wire to clothespin Cut a piece of black electrical wire, strip both ends, and tape one end to one tip of the clothespin. Step 3: Connect negative pole to other tip Locate the wire running from the negative pole of the noisemaker—the pole marked with a minus sign—and connect it to the other tip of the clothespin. Tip If your noisemaker doesn't come with wires already attached, just cut and strip another piece of your own to use. Step 4: Connect wires to battery holder Locate the wire leading from the positive pole of the noisemaker and connect it to the battery holder. Now do the same with the remaining black wire coming from the clothespin. Tip You've just built a completed circuit. Connect the battery to make sure it works. Now DISCONNECT IT!

Now string the fishing line across the strongest crease, tie it off, and finish the triangle. Step 6: Put folded paper inside clothespin Put the folded paper inside the clothespin. Step 7: Tape to inconspicuous place Tape the clothespin, noisemaker, and battery to an inconspicuous place in your coworker's path. Step 8: Run fishing line to secure anchor Run the fishing line to a secure anchor across the way. Step 9: Wait for "Mr. Chirpy" to head your way Now just wait for "Mr. Chirpy" to head your way.
