Pass the Vegetables, Please - S3-E3
Visible crew/equipment: As Mary Ann discovers she's blowing bubbles as she talks, you can see part of the device just to the left of her neck, and the bubbles can be seen coming from beside her left cheek.
Gilligan's Personal Magnetism - S3-E21
Visible crew/equipment: Toward the end, the group is around the table, talking about Gilligan. Then they see a pear and a bunch of grapes float over to a plate at the head of the table. Skipper goes over and addresses the invisible Gilligan. If you look at the top of the hut, you can see the wires used to make the fruit float. Also, earlier in the hut with Ginger, when Gilligan bit the pear, you can see the wire holding the pear as it shakes after the bite.
Visible crew/equipment: As Gilligan runs along, stuck in the hollow log, the wires holding it up and guiding it are visible toward the top of the shot.
Chosen answer: It looks like a mistake to me I see it when the Professor is put into a trance, but it is not there later.
