Hello there! My name is Cole Geryak, and this is first edition Disney Extinct Attractions, an unofficial journey through Disney attractions that have left the parks! What I will attempt to do through this post and future posts is help bring some light onto former Disney park attractions, both shows and rides, so that these attractions don’t fall off into a trash can of attractions like Woody in Toy Story 2.


Without further ado, it’s time for an Adventure Thru Inner Space.

During the middle of the 1960s, Tomorrowland in Disneyland was slowly turning into Todayland. The whole atmosphere of the land began to feel outdated, leaving park guests wanting more. Since 1957, Walt, with his mind also on expanding the park, had been thinking of adding in an a pseudo-extension to Tomorrowland known as Science Land, alternatively known as Adventures in Science. One of the headlining attractions of this land would be known as “Micro-World,” a journey where guests would sit on protozoa and travel through a drop of water.


Slowly but surely, Walt got consumed by other ventures such as the Florida Project and the 1964 World’s Fair, and Science Land began to fall by the wayside. But the idea for Micro-World stayed locked away in the Imagineers files as a project for another day.

That day finally came when Walt, fresh off his massive success at the World’s Fair, saw Tomorrowland and knew that he needed to upgrade it. Having not gained an attraction in the past 6 years, Tomorrowland was in great need of the innovation that the land prided itself upon. Hence, New Tomorrowland 1.0 was born.

With this restructuring, it was finally time to bring Micro-World into the fold of Disney attractions. Rebranded as Adventure Thru Inner Space, the attraction opened on August 5, 1967 along with the rest of the new and improved Tomorrowland.


If that building looks familiar to you, it’s because the building currently houses Star Tours-The Adventure Continues at Disneyland Resort. As you can see, the attraction was presented by Monsanto, a sustainable agriculture company, which also sponsored such attractions as The House of the Future and The Hall of Chemistry. One note about the Hall of Chemistry is that it gave some guests their first look at atoms and the molecular structure of compounds. These were not yet commonplace things to learn about in school, and then Adventure Thru Inner Space took that one step further by taking you inside a water molecule, giving guests a first-hand look at the molecular structure that compound.

I’m not going to dive deep into the story because I do not want to spoil it for those who want to watch the virtual ride through of the attraction found here, but a brief synopsis is that you travel through the Mighty Microscope and slowly shrink smaller and smaller, while examining a snowflake. Throughout the journey, you begin to see more of the molecular structure as you dive farther into the structure of the water molecule.

The virtual ride through is actually an amazing resource that I cannot recommend enough! You feel like you experience the whole attraction, and the design behind it is fantastic. That being said, the actual attraction had some pretty fantastic minds behind it such scriptwriter X Atencio and special effects guru Claude Coats, both Disney Legends and large parts of the creation of the Haunted Mansion and Pirates of the Caribbean. It also featured the incredible voice work of Paul Frees, best known as the Ghost Host, which you can actually hear in the link. Finally to top it all off, the attraction ends with the song “Miracles from Molecules” composed by the great Richard and Robert Sherman. While not their best song, it is still extremely catchy, and once you hear it you won’t be able to get it out of your head!

Once of the coolest parts of Adventure Thru Inner Space is the Mighty Microscope.


Guests were shrunk with this microscope to go on their journey. Looking at this picture and the concept art from Micro-World, the second picture included, shows that the microscope remained a constant factor throughout the development process. What I think is one of the coolest parts is the mini-Omnimovers in the clear portion of the microscope. Some guests were reportedly frightened that they were actually going to be shrunk because of how convincing the illusion was!

Speaking of Omnimovers, Adventure Thru Inner Space was actually the first attraction to make use of the now Disney staple of the Omnimover ride system. The designers wanted a way to increase ride capacity while also being able to control where viewers could look.

One other interesting tidbit that made the attraction unique was that when it opened , it was one of the few free attractions in the park. The park was still using a ticketing system where different attractions would cost an amount of tickets in addition to the admission that you paid for the park. Five years after opening, in 1972, the attraction started costing a “C” ticket, so still a relatively lower-cost ticket.

Unfortunately, Adventure Thru Inner Space closed September 2, 1985 to make room for the first incarnation of Star Tours. However, the Mighty Microscope lived on through Star Tours.


Right near the middle of the screen next to the building on the right-hand side, you can see the Mighty Microscope! The Imagineers gave a fitting tribute to the attraction that it replaced. Fans of Inner Space were worried that the Mighty Microscope might be gone for good with the renovation of Star Tours into Star Tours-The Adventure Continues, but no need to fear…



The love for Adventure Thru Inner Space lives on for those in the know. This attraction should be remembered for its innovative nature and its clever way of both teaching guests, while also taking them on a journey that they could not experience anywhere else!

For more information on Adventure Thru Inner Space, here is a 30-minute documentary about the attraction with interviews from some of the Imagineers behind it.

Ok so that about wraps it up for this segment of Disney’s Extinct Attractions. I’m more than open to any feedback you have, whether it is good or bad because I want to be able to shape this to what you want! If you have any attractions that you really want to know about feel free to contact me at cgeryak13@gmail.com, so I can write about those sooner. Also, there is a Facebook Group if you would like updates on when new posts come out, so feel free to join that!
