Adventure Thru Inner Space was an attraction in Disneyland's Tomorrowland, presented by Monsanto Company. It was the first attraction to utilize Disney's Omnimover system. The ride simulated shrinking guests to the size smaller than an atom (the "inner space") before taking a tour of snowflakes at molecular and atomic levels. Adventure Thru Inner Space opened on August 5, 1967, as part of the New Tomorrowland, and closed in 1985 to make way for Disney and George Lucas's new Star Tours attraction, which opened in early 1987. The attraction was narrated by Paul Frees, who also lent his voice to the Haunted Mansion attraction, another Omnimover attraction which is still open to this day. Synopsis The attraction was designed to simulate humans shrinking to a size smaller than an atom (the "inner space"). As patrons waited in line they saw those before entering one end of the Monsanto Mighty Microscope. The other end of the Monsanto Mighty Microscope had a glass tube in which the supposedly miniaturized riders could be seen moving through. The microscope was aimed at a panel beyond which snow could be seen falling. Upon boarding their 'Atommobiles', riders were greeted by the voice of an unseen scientist (Paul Frees) who explained: "I am the first person to make this fabulous journey. Suspended in the timelessness of inner space are the thoughtwaves of my first impressions. They will be our only source of contact once you have passed beyond the limits of normal Mag-ni-fi-ca-tion." The Atommobile entered the Monsanto Mighty Microscope and began to shake back and forth as the riders entered the darkness. As their vision returned, the riders saw giant snowflakes all around them, some still spinning as they fell. As they continued to shrink, the narrator exclaimed, "I am passing beyond the magnification limits of even the most powerful microscopes. These are snowflakes – and yet they seem to grow larger and larger. Or can I be shrinking – shrinking beyond the smallness of a tiny snowflake crystal? Indeed, I am becoming smaller and smaller!" The snowflakes took on a crystalline form, eventually becoming large enough to cover the entire field of the riders' vision. Approaching the walls of ice crystals, the voice of the unseen scientist marveled, "These tiny bits of snowflake crystal tower above me – like an enormous wall of ice. Can I penetrate this gigantic prism? And yet, this wall of
