Bill Nye careens around a roller coaster, furiously pedals his bike on the "Tour du Science," and parodies the Jackson 5's "A-B-C 1-2-3" with "ABCs of Machinery," to show that simple machines doing complicated things can be found everywhere. The DVD has extra features: fully indexed "chapters" correlated to national science standards, interactive glossaries and quizzes, bonus footage of never-before-seen segments, interviews and demos, Spanish translation, and on-disk implementation guide.
