Any rare event creates a number of challenges when it comes to manufacturing and supply chains. We're seeing a pretty historic "spike" in demand for products like the inexpensive glasses that allow one to safety view the eclipse (our friends in the totality zone can look at the totally-eclipsed sun safely, but that's the only time).

You could call it "supply chain challenges" or a "lack of planning on my part," but I cannot find eclipse glasses anywhere. There are MANY articles online about this widespread problem -- it's been impossible to buy "eclipse glasses" anywhere. Why is this? What could have been done?
