Ep 4. Temporary Metal Fences, Asphalt Shingles, Expanded Polystyrene Products, Hard Candies

In season 2 episode 4 of How It's Made, viewers are taken through the fascinating process of creating temporary metal fences, asphalt shingles, expanded polystyrene products, and hard candies.

The episode starts with a visit to a factory specializing in creating temporary metal fences. Using heavy-duty machinery, workers expertly cut and shape long metal bars into individual pieces before assembling them into a fence. The process is precise and efficient, from the welding of the metal bars to the attachment of stabilizing feet. The final product is a sturdy and secure fence that can be easily transported and installed at construction sites or events.

The next segment explores the world of asphalt shingles, a common roofing material. Viewers learn how a combination of asphalt and fiberglass are layered to create shingles of varying thicknesses and colors. Large machines cut and shape the shingles before they are baked at extremely high temperatures to ensure durability. The intricate process of adding texture and granules for traction is also highlighted, culminating in a finished product that is designed to withstand extreme weather conditions.

The show then shifts focus to the production of expanded polystyrene products, commonly known as EPS foam. This material is used in a variety of products, from foam cups to insulation. The production process involves heating and expanding polystyrene beads with steam, which are then molded into specific shapes and sizes. The result is a versatile and lightweight product that is also eco-friendly. The episode follows the journey of EPS foam from the factory to its various applications, including packaging and insulation for buildings.

Finally, How It's Made takes viewers through the intricate and sweet process of creating hard candies. From the mixing of sugar and corn syrup to the addition of flavors and colors, the process is both scientific and artistic. The sugar mixture is heated and cooled repeatedly, causing crystals to form and creating the hard texture of the candy. The candies are then cut and wrapped with precision and care. The segment gives viewers a glimpse into the elaborate process of creating visually appealing and flavorful hard candies.

Overall, How It's Made season 2 episode 4 offers an exciting and informative look into the processes behind the creation of temporary metal fences, asphalt shingles, expanded polystyrene products, and hard candies. The show is sure to leave viewers with a newfound appreciation for the skill and technology required to produce everyday items we often take for granted.
