'Spy Kids' adds smell with '4-D' Aroma-Scope

In this film image released by The Weinstein Co., Mason Cook is shown in a scene from "Spy Kids: All the Time in the World in 4D." Filmmaker Robert Rodriguez is using "Aroma-Scope," to add scents to the new "Spy Kids." Viewers are given scratch-and-sniff cards with circles numbered 1 to 8. When a number appears on screen, they rub the corresponding circle on their cards, which give off a whiff matching what the characters are smelling. (AP Photo/The Weinstein Co.)
