'Spy Kids: All The Time in the World in 4D' is coming your way in August, and now moviegoers will have the chance to enhance their experience in a special way.

What's the fourth dimension of the movie? Smell. That's right, you'll be able to get a whiff of various scents during different scenes of the movie with the help of scratch-and-sniff Aromascope cards.

Like 3D glasses, the cards will come free with your movie ticket and will feature eight numbers that match up to moments in the movie. When the numbers flash on the screen, that's when you can scratch and sniff the corresponding number on your card. Pretty cool, right?

'Spy Kids: All The Time in the World' hits theaters this summer on August 19. Fans who want to get even closer to the action can head to Moviefone to enter their contest in which one lucky winner will get to fly to Los Angeles and interview members of the cast. Get more details here. Hurry, the sweepstakes deadline is July 12.
