The father of modern rocketry, Robert H. Goddard (Beakman), explains how rockets are propelled combining Newton's Third Law of Motion -- "For every action there is an equal and opposite reaction" -- with a mixture of fuel and liquid that can burn in airless space. Also, Beakman demonstrates how you can make a soda-bottle rocket at home, describes how ear wax keeps ears debris-free and answers prickly questions such as "Why do I feel 'pins and needles' when my foot falls asleep-"
