1. Choose a round container, a bottle cap or some other adminicle as you like, just round is ok. Bind the aluminum wire on the round object; leave over two tails of the two terminals and cut of the wire.
2. Loop the longer tail. using the flat nose plier and clamping the shorter tail ,coiling on the longer tail and so that it will form a complete circle and without gap.
