Aromascope is the use of scents to enhance the experiences of users. Spy Kids 4: All the Time in the World will be one of the first films to use Aromascope to let us smell along with sight and sound for our senses. As one of the first films to implement "Aromascope," Spy Kids 4 will use scratch-n-sniff cards to add olfactory options to our movie-viewing experience. Numbers will flash at key points; the corresponding numbers on the cards will alert us to scratch the matching panels on the cards.
