Cut out the cans’ pop-tops and bottoms. Do not cut the body part into pieces, because they will be used in later parts

Some body part still remain on the tops, so cut with the small scissors and tear them off.

Note: when you tear the remaining parts, use a cloth to protect your hand from getting hurt by the sharp edge.

Cut off the remain body part on the bottom, then polish the edge of the bottoms with sand paper

Keep the can body parts for next step.
