Popular children's television scientist Beakman (Paul Zaloom) begins this compilation by encouraging inquisitiveness: "We can't have answers without questions!" The video is a series of scientific demonstrations in response to viewer questions ("How do rockets work?") and challenges posed by Beakman himself ("I challenge you to balance two forks and a toothpick on the tip of another toothpick"). There are a smattering of "fast facts" and a few role playing sequences in which Mr. Zaloom plays historical or fictional characters. Most of the experiments focus on physical science. A playing card illustrates air pressure by holding water in an inverted glass. Beakman shows us how to build a homemade oscilloscope and a camera obscura that can be worn on your head. Viewer questions are addressed in several modes. Verbal explanations are given with comic gestures, silly sound effects, and inane commentary from Beakman's daffy sidekick, Lester the Rat. In one segment, Mr. Zaloom plays the mythological character Narcissus with humorous vanity as he explains how mirrors reflect light.
