Viewers enter the Imagination Institute's theater for the Inventor of the Year Award Ceremony, in which professor Wayne Szalinski is receiving the award. Attendees are asked to don their "safety goggles" in preparation for the scientific demonstrations. The show opens with the crew of the show searching for Wayne, when he suddenly flies on stage miniaturized and in a transportation device called a Hoverpod.
He accidentally drops the control box and sends the machine flying off behind the stage out of control. The Hoverpod comes back and destroys the neon Imagination Institute open house sign over the audience (at first only some letters are knocked out, leaving "NERD" spelled diagonally).
Wayne's son Nick demonstrates some of his father's other inventions to kill time while the crew searches for Wayne. This does not go smoothly, and the audience ends up screaming with loose mice running under their seats and a holographic "Holo-Pet" lion in their faces. While the demonstrations go awry, Wayne manages to use his shrinking machine to return himself back to normal size. He brings out the machine to demonstrate its uses by shrinking a family's luggage, saving space when traveling.
Unfortunately, the machine goes out of control and shrinks the audience. The viewers are antagonized by obstacles such as Wayne's younger son Adam taking a picture of the audience with a blinding flash and picking up the theater to "show the little people to Mommy." Then Nick's python Gigabyte, much larger than the miniature audience, nearly eats the theater. Quark, the Szalinski's dog, then chases Gigabyte away. Luckily, Wayne fixes the machine and returns the audience back to normal size, but Quark is momentarily affected by the enlarging ray and then runs backstage out of sight.
Wayne accepts his award and begins his speech, but he is interrupted by Nick warning of a "big problem." The now giant Quark walks out onto the stage and the curtain closes while viewers hear the Imagination Institute's crew trying to stop the dog from crushing the theater. Quark then finds his way through the curtains and sneezes on the audience for the finale. As the audience leaves, they can hear the commotion from backstage continue.
This show has been replaced with Captain EO at all Disney themed-parks.
