Follow the steps below:

1.
Cut two strips of
unwrinkled aluminum
foil, each the size of
the one shown below.

2.
Put them on a piece of
thick cardboard and
use a sharp object to
make a hole near one
end of each strip

Also make a small
hole in the center of
the plastic lid.

4.
Cut a piece of stranded wire
to about the same length as
the one in this drawing. Strip
the insulation from each end
and twist all the strands at
one end.
At the other end, divide the
strands into two groups. Twist
each group separately and
form two hooks, as shown.
