Guests enter the iconic white pyramid into the first phase of the queue which features a Museum of Microscopic Marvels! All presented with retro futuristic, optimistic, 60s/70s tone of the original ride and of this ride, but updated with modern science and sensibilities! The exhibits here are a mix of real life and sci-fi experiments featuring nano-scale wonders and almost magical experiments with shrinking and growing. Visually, this area resembles the "windows" section of WDW's Space Mountain queue with each window showing a different exhibit.

Some of the highlights include a showing of IBM's World's Smallest Movie (a stop motion film made by moving individual atoms), shrunken scientists manipulating carbon interstitials in metals by hand to create alloys, and a display on the single molecule nanocar created primarily out of Buckyballs (clusters of carbon nano-particles).

After passing through the more polished museum, guests enter into a workspace for the scientists for the experiment guests are about to take part in. This section is much more lived in feeling and inside jokes between scientists and little touches like desk toys to make it seem more realistically like a place real people work in. There are a few personal projects, but for the most part all the work on display is about snowflakes on a micro-scale. This serves as a "walking pre-show" prepping guests for what they need to know for the ride without needing any dialogue or a video.

While the ride does fictionalize things a bit to make a better experience, there is a solid effort to keep it grounded in real science. This section goes through the basics of the cellular, molecular, atomic, sub-atomic, and quark levels for a snowflake. What the scales are, what is happening, what these are, etc. As well as basic water/snowflake facts like melting points.

The final phase is visually very similar to the iconic loading station of the original. Though laid out similarly to WDW's Rock n' Rollercoaster's load station. Guests see the Mighty Microscope pointed at a snowflake and see cars enter into it before launch through. From this angle and with the use of well timed projection tech, it looks like the rollercoaster cars are really launching into the snowflake at high speeds! The Peoplemover also passes by here adding to the exciting kinetics of this room and building the anticipation as guest board their Atom-Mobiles!

The tech in this room attempts to stay somewhat grounded. Realistic lab safety signs advising safety goggles and lab coats be worn can be seen throughout. But this is easily the most fantastical section of the queue with the microscope as a stand out set piece transitioning from the real science focus of the queue to the more over the top (but still centered around reality) ride.

Trains head out, turn left and sit on a launch track awaiting clearance.

Atom-Mobiles near the Mighty Microscope, which looms before them with a high-tech tunnel like the CERN particle accelerator. A large screen on the wall ahead depicts the single snowflake which sits under the Microscope’s lens, which we are about to enter. “Your attention, please. Your adventure through Inner Space is about to begin. Through the Mighty Microscope, you will travel to a universe housed within a single snowflake. Now prepare to pass beyond the limits of normal...”

Trains enter the InnerSpace Mountain dome and propel upwards at top speeds to a height of 75 feet, then make a banked turn left and rush down a straightaway with a downwards slope.

At the cellular scale, glowing azure snowflake crystals line the aether like stars in outer space, spinning beautifully. The further Atom-Mobiles rush along, the larger these snowflakes become.

Trains reach a straight section of track where they rush through two bunny hills, providing riders with airtime. Another left bank follows this.

After a brief section of blackness, the whole world is dotted by a 3D geometric array of H2O molecules frozen in place and glowing from within. (The one oxygen and two hydrogen atoms resemble Hidden Mickeys.) The molecules seem to grow as riders continually shrink.

A straight & flat mid-course brake run carries trains into the next block section.

Atom-Mobiles rush towards a massive oxygen atom dead ahead, orbited by neon electrons. The vehicles enter the atom’s central nucleus as though through a portal.

Trains pick up speed as they rush downwards through an increasingly sharp helix spiral leftwards.

At the atomic level, riders spiral through the interior of the oxygen atom as spherical neutrons burn like planets all around them.

A banked turn to the right should prove pleasantly disorienting after so many left turns. This is instantly followed by a snappy S-turn element which continues trains towards the right.

Riders suddenly, violently shrink to the subatomic scale as they enter the inside of a neutron! The world becomes a psychedelic kaleidoscope of swirling colors, like a series of disorienting spinning tunnels which riders twist through to and fro.

Trains slow down onto a brake run which leads onto a switch track.

Smaller still, protons whiz past riders very much like the star field projections on Space Mountain, but with some otherworldly fractal patterns as protons curl in on themselves.

Trains rest for a moment on a dead end launch track.

The world again becomes utter darkness, until a single quark sits motionless in front of riders glowing bright like a massive Sun lit from within. “Warning! Warning! The snowflake is melting! Enact emergency regrowth procedures! Escape from Inner Space NOW!”

Trains unexpectedly launch backwards at 35 mph! They travel the final block course backwards, rising up an upwards airtime bunny hill, then following left banked turns backwards. The track itself is less intense in this section, but the backwards sensation makes it a fitting physical climax.

The backwards launch signifies that the Atom-Mobiles have started to grow, and are returning to their original scale. Riders rush through a repeat of earlier microscopic sights. Since the snowflake is melting now, the water molecules circulate in random disarray. The whole minuscule world is erupting into chaos!

Trains slow down on the final brake run straightaway. This track parallels the storage & maintenance shed.

Reaching the crystal scale, riders find themselves within an enormous Niagara of oversized melting water! A glass tunnel surrounds trains, with water hoses blasting from outside lit in a spectrum of wild colors.

Guests exit the cars into a space that is very sleek and modern. Displays can be found of practical applications of nano-technology and companies are invited to showcase what they can do with it. Obviously, carbon nanotubes are bound to be the most prevalent and most exciting example due to its strength and flexibility. It is still used rarely due to the prohibitive costs, but the possibilities for it are nearly limitless! We can already see these used in bicycles, sportswear, and the military, but those are really just the beginning. Even before we understood what they were, we were using them! Carbon nanotubes have been discovered to be the secret ingredient that makes Damascus Steel special in the 17th Century.

There is also a game here based on the Nanocar teased in the queue. Kids of all ages can learn some basics of nanoparticles as they build their own virtual nanocar at touch screen kiosks. They can then go to race them in an interactive game similar to the one found in the Test Track post-show but with a more educational bend to it.
