CD ROM Fish Craft

Instructions to make a cute, hanging fish out of old Cds.

Materials Needed:

2 Old CDs
Construction Paper
Large Wiggly Eyes
Glue
Yarn or Fishing Line

Instructions:
Using whatever color of paper you prefer, cut out the fish's lips, fins, and tail (. Glue the lips and fins to the side of the cd with the writing on it (figure 2). Set aside one of the top fins.

Cut a piece of yarn or fishing line 3 - 4 feet long. Tie a knot in one end. Run a line of glue from the hole in the center of the cd up to the top edge of the top fin that is glued onto the cd. Lay the yarn or fishing line on top of the glue so the knot is in the hole in the cd. Glue the extra top fin on top of the other top fin to cover the yarn . Spead glue all over the side of the cd that everything else is glued to. Set the other cd on top of the glue and match up all the edges. Make sure you have the side of the cd with any writing facing down into the glue.

Glue the wiggly eyes on your fish as shown in figure 6. Glue one on each side of his head. If you don't have wiggly eyes, you can also use a small white pom-pom and a black bead. This will give your fishes eyes a more 'buggy' look! The last thing you need now is a fin on the side of the fish! You will make these by using a 5 x 6 inch piece of construction paper. Accordian fold the paper. Using figure 7 for an example, you would fold the paper back and forth on the white lines. Once it is fold, hold the folds together and slip in through the hole in the center of the cd. Center the paper in the hole and unfold the ends a bit to fluff them out. Add a little glue to hole of the cd and the paper. You can now hang up your completed fish.
