I use the water worn bottoms of broken bottles found
at a beach, to make a colorful wind chime.
First collect 5 or 6 largish (2" across) pieces of beach
glass. Using two part quick set epoxy, glue a jump
ring to one edge of the glass piece. Allow to dry.
Once all pieces are done and dry, tie on fine fishing
line and string from a piece of drift wood. Hang the
drift wood in a tree or on the porch.
You can varnish the glass for a prettier finish.
