Step 1: Make Three Fins
A. Cover the fins
Cut out the template.
Tape the fin template to the foil.
B. Slit the back of each fin support. Use a craft knife
to slit the back of the three fin supports. You can
also snip off the back edge with scissors if you don't
have a craft knife.
C. Insert fins into fin supports. Push the fins all the
way into the fin supports. You can hold them in with
a small piece of tape if needed.
D. Tape the fin holder to the bottle. Wrap the fin
holder around the bottle as shown. The bottom edge
should be even with the bottle opening. Use strips of
silver foil or tape to seal the seam.
