ice only seems smooth and solid. From this tiny viewpoint, I can see that nothing is solid, no matter how it appears." Indeed, it then became obvious to the Atommobile riders that the ice crystals were not solid, but a lattice-like structure that they pass through. "And still I continue to shrink! What compelling force draws me into this mysterious darkness—can this be the threshold of inner space?" Next, the riders encountered a matrix of spheres appearing in columns and rows of infinite length. "What are these strange spheres?" asked the narrator. "Have I reached the universe of the molecule? Yes, these are water molecules – H2O. They vibrate in such an orderly pattern because this is water frozen into the solid state of matter." As the travelers continued to shrink, the molecules became larger, and took on a peculiar Mickey Mouse shape. "These fuzzy spheres must be the atoms that make up the molecule – two hydrogen atoms bonded to a single oxygen atom. And I see that it's the orbiting electrons that give the atom its fuzzy appearance. And still I continue to shrink." The scientist wondered, "Is it possible that I can enter the atom itself?" As the atommobile entered the atom, a storm of lights flashed past on all sides at impossible speeds. "Electrons are dashing about me – like so many fiery comets! Can I possibly survive?" Suddenly the frenzy of the electrons passed, and the riders found themselves in a large, empty space, surrounded in the distance by a sphere of slow-moving lights. "I have pierced the wall of the oxygen atom," continues the Narrator. "I am so infinitely small now that I can see millions of orbiting electrons. They appear like the Milky Way of our own solar system. This vast realm, THIS is the infinite universe within a tiny speck of snowflake crystal." A large pulsating red ball could then be seen inside the atom. "And there is the nucleus of the atom! Do I dare explore the vastness of ITS inner space? No, I dare not go on. I must return to the realm of the molecule, before I go on shrinking...forever!" The riders then began the return journey to full size, but were soon greeted with the sight of water molecules swirling rapidly. The scientist sees this as a discovery and says: "Ah, how strange! The molecules are so active
