As the solar eclipse approaches, one of the busiest factories in America just keeps getting busier. They’re trying to keep up with the demand for glasses to safely watch the solar eclipse on August 21. American Paper Optics in Memphis, Tenn., began preparing for the solar eclipse two years ago. In the last several weeks, the factory had to triple its staff and stay open around the clock. Now people are even turning to their own crafting skills to create makeshift glasses.
