When glasses run out: safe DIY eclipse viewing tricks

With eclipse glasses scarce, the article outlines safe DIY projection methods to view the Sun: poke a pinhole in cardboard to project an image on paper, or create a simple box with a foil aperture, and even use tree leaves' dappled light or a kitchen colander to cast Sun images. These tricks let you watch the eclipse safely without looking directly at the Sun, and have NASA approval; avoid unfiltered filters, CDs/DVDs, or stacking sunglasses, and remember to keep your back to the Sun.
