You can use your own fingerprint to model a distinctive pattern of zebra stripes. Rub the lead of a pencil back and forth across an index card. Then rub one fingertip back and forth over the pencil marking. Cover the smudged fingertip with a piece of transparent tape. Press the tape firmly against your fingertip. Carefully remove the tape and press the sticky side against a second white index card. Use the pencil to draw a frame around the fingerprint. Then add a tail, as shown.
