In Clean Streets Ahead! How Road Sweepers Tackle Dirt, presenter and motorbike racer Grace Webb investigates the outside and inside of a road sweeper, a vehicle with three big brushes that sweep dirt off the road. Road sweepers spray powerful water through nozzles to wash away stubborn grime, and for tough dirt, there's a giant vacuum in the back that collects everything into a compartment called the hopper! This video is excerpted from BBC’s Grace’s Amazing Machines, a children’s show that introduces kids to some of the biggest, fastest, and most amazing machines in the world.
In The Fin Garden of Kashan, host Joanna Lumley visits a garden that was built in 1590 by channeling an ancient spring to bring flowing water to the desert. The water in this garden flows even during times of drought. The technology used to bring water to the surface has since been used in many other parts of the world. This video is excerpted from BBC’s Joanna Lumley’s Silk Road Adventure, a documentary series uncovering the rich history and cultural treasures of the Silk Road.
In Chili Production in India, presenter Cherry Healey visits Guntur, India, to explore a chili farm and factory. Her eyes are watering, but that doesn’t stop her from helping pick, process, and grind the chili plants into powder. Learn how chili flakes and powder are made, and how India supplies the entire world with chili. This video is excerpted from BBC’s Inside the Factory, a series that takes viewers behind the scenes in the factories that make our favorite products.
