Ep 12. Top & Bowler Hats, Solar Water Heaters, Sticky Buns and Electrostatic Speakers

In season 11 episode 12 of How It's Made, viewers are taken on a journey through the manufacturing processes of four distinct and unique items - top hats, solar water heaters, sticky buns, and electrostatic speakers.

The episode begins by delving into the creation of top hats, a quintessential accessory in the world of fashion. Starting with felted fur or wool, the material is shaped on wooden hat blocks to create the classic top hat shape. The hat is then steamed to set the shape, and trimming and lining are added to complete the final product.

Next, the episode switches gears to focus on solar water heaters, a sustainable alternative to traditional methods of heating water. The process starts with a solar collector panel, which absorbs the sun's energy and heats up water within a network of tubes. This hot water is then transported to a storage tank, where it is ready for use. The episode highlights the various components that make up a solar water heater system, including the solar collector panel, storage tank, and various valves and pumps.

Moving on to food manufacturing, the episode dives into the creation of sticky buns - a sweet and gooey pastry treat. The process starts with mixing together flour, yeast, and sugar to create a dough. This dough is then rolled out and sprinkled with cinnamon and brown sugar. The dough is then rolled up into a spiral shape and sliced into individual buns. The buns are then topped with a sweet glaze and baked in the oven to give them their signature sticky texture.

Finally, the episode explores the process of creating electrostatic speakers, a type of speaker that operates by producing an electrical charge to move air and create sound. The process starts with a thin film made from a conductive material, which is then coated with a thin layer of insulation. This process is repeated multiple times to create the speaker's diaphragm. Once the diaphragm is complete, it is mounted onto a frame with magnets, which move the diaphragm back and forth to create sound. The episode highlights the intricate nature of these speakers and the precision required in their production.

Overall, season 11 episode 12 of How It's Made offers a diverse range of manufacturing processes, from traditional fashion accessories to cutting-edge technology. Viewers will gain a newfound appreciation for the intricacies and ingenuity involved in the creation of everyday items we often take for granted.
