Já está confirmado que Jeannie pode fazer sua mágica sem cruzar os braços, mas aparentemente ela precisa piscar. Do episódio da quinta temporada "O Sangue de uma Jeannie" :
As genies have red and green blood, Roger masquerades his arm as Jeannie's so that she can get a certificate of perfect health to be eligible to marry Tony. A man at the jeweler's store steals Tony's wallet so Jeannie blinks the jeweler's store into his office. Roger stops anyone leaving as they will walk out into a NASA corridor. Jeannie's eyes have been dilated and she can't blink but when she can she makes the thief return the wallet and blinks the store back. Roger apologizes and leaves when a man walks in from the street.
