CD Rom Fish craft - I made these with a group of children using 2 CDs. Glue the fins etc as instructions then glue another CD on top, hiding the ends of the fins. Fan fold some paper (about 30 cm long and 20 cm wide) starting on the long end. Once folded feed through the hole and open out a bit on either side to create pectoral fins. We then attached them all to wire coat-hangers to create a lovely glittery fish mobile.
