There's a lot more blowing around than hot air when Bill Nye the Science Guy goes parachuting and sailing to show the relationship between the Sun, Earth, wind, and weather. Bill visits a wind farm and checks out way cool windsurfers to show some of the ways to harness the power of the wind. 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. .
