Herb turns on Beakman's World, a show Don thinks is a telethon for guys with weird hair. Beakman reveals that flies only live for two weeks unless someone finds them first.
Chris Holloway of Tulsa, Oklahoma asks about levers; Beakman calls them simple machines that help people work easier. While trying to explain, a boulder from his rock collection in the attic lands on a teeter totter on the ground floor. Beakman uses the incident to show the fulcrum in a lever as well as the areas of resistance and effort. He says the teeter-totter used to move the boulder is a first class lever as Josie and Lester do the work. First class levers have a fulcrum in the middle and include clippers, scissors and tire jacks. Second class levers have the fulcrum on the end such as a wheel barrel or bottle opner and third class levers don't have fulcrums; you do the work, such as sledgehammers, baseball bats and golf clubs. Lester shakes up a soda and gives it to Beakman. It explodes of course, but Beakman is too mature to retaliate.
In Beakmania, Beakman reveals tapeworms can get as long as thirty-two feet long. The human brain works on the same amount of electricity as a 12-watt bulb. Snails have 25,000 teeth and in New York City, people bite people more often than rats bite people.
In the Beakman Challenge, Beakman challenges Lester to balance two forks on a toothpick, a feat he finds impossible. Beakman accomplishes it by putting the forks together and balancing them on their center of gravity.
Shannon Jancula of Pittsburgh, Pennsylvania asks how television workswhich brings a visit from the late Philo T. Farnsworth who dreamed the invention up at 14 and developed it when he was 21 using Marconi's radio principal. He also says he predicted it'd be used for live news, sports coverage and advertising, but he never guessed it'd be used to feature Lester. He explains that TV doesn't get a picture, it puts one together using instructions and demonstrates by having Lester send messages to Josie to plip tiles into an image. TV uses the same priniple, but it creates thirty images a second to create a picture moving images.
In the closer, Beakman uses the moving image principle to create a cartoon flip-book with a pad of paper. Don and herb compare Antarctica to a refridgerator with the clouds as ice makers and the sun as the light inside the freezer.
