This show had it all - highly entertaining, educational, and just plain fun all rolled into one. The funny thing is that its target audience was obviously children, but I was 22 when it first aired, had no children of my own, and throughly enjoyed the show.
Most if not all of every show revolved around questions posed by the audience, i.e., children. The hosts (primarily Beakman) would proceed to answer by performing basic, yet interesting scientific experiments or explain the prevailing theory, with a thick dose of humor over all.
From all the great shows, the one I remember most was this question - "why do farts smell bad?" Now naturally, this question was fodder for all sorts of jokes by the sidekick guy in a rat suit. But Beakman, as always, tackled the question with a fantastic blend of serious science and circumstantial humor. I've never heard such a question asked on a children's show before, but it was handled very well, with the anticipated humor not completely detracting from the serious matter of providing the answer.
As a young adult I was amazed by this show, and even got up regularly, on Saturday morning no less, to see what Beakman had in store next. The show was cleverly designed to please both adults and children, and certainly worked its magic on me. Definitely give this one a chance.
