With a viewer question about why sweat smells, Beakman and his lab assistants work up a sweat to find the answer. Beakman demonstrates the functions of perspiration by comparing our bodies to car engines. Like the radiator in a car, perspiration helps maintain a healthy body temperature. But that's only the half of it; to find out why Lester smells the way he does after a science work-out, Beakman discovers the culprit behind the odor. Millions of bacteria and their waste create that familiar scent of sweat. Turning to Beakmania, Beakman discovers how much food an average person consumes in a life time (50 tons of food and 11,000 gallons of liquid) and why people have nose hair. Then, Chef Art Burn (Beakman dressed as the culinary wizard) gives away the secrets of his recipe for paint. Using colored chalk, water, a pot and some glue, Beakman shows how easy it is to discover the artist within.
