In the first episode of the season, we learn about the making of binoculars--which is, actually, a pair of hand-held telescopes--and the fabrication of party sparklers that are indispensable on every celebration. Next, we discover how Wellington boots, rain boots or just plain rubber boots are made, thanks to the vulcanisation progress. Finally, we learn all about one of the most important tools in any construction site: the circular saw blade.
