Adventure Thru Inner Space.
Adventure Thru Inner Space was another ride sponsored by the Monsanto Co. at Disney Land. Its another lost treasure of the era, and it was retrofuturistic in all the best ways possible. Do my work for me Wikipedia:
The attraction was designed to simulate humans shrinking to a size smaller than an atom (the “inner space”). As riders waited for their journey into the atom, they were able to see other riders entering one end of the Monsanto Mighty Microscope. The other end of the Monsanto Mighty Microscope had a glass tube in which miniaturized riders could be seen moving across. 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.”
