Ummm… I remember not being allowed to view a solar eclipse when I was in elementary school. We took paper plates and wrapped them in aluminum foil, in some way that allowed us to see a mirror image of the eclipse safely.
According to my memory of my teacher’s words, looking at an actual solar eclipse can be blinding.
Sorry to be a wet rag on the flame … maybe my memory is incorrect and a quick online search will show that it’s indeed safe?
