“Make a simpler version of the solar eclipse viewer with two thin but stiff pieces of white cardboard. Punch a small, clean pinhole in one piece of cardboard and let the sunlight fall through that hole onto the second piece of cardboard, which serves as a screen, held below it. An inverted image of the sun is formed. To make the image larger, move the screen farther from the pinhole. To make the image brighter, move the screen closer to the pinhole. Do not make the pinhole wide or you will only have a shaft of sunlight rather than an image of the crescent sun. Remember, this instrument is used with your back to the sun. The sunlight passes over your shoulder, through the pinhole, and forms an image on the cardboard screen beneath it. Do not look through the pinhole at the sun.” Or build the complicated model: https://www.nationalgeographic.org/activity/build-a-solar-eclipse-viewer/

So Mooni is jealous of an eclipse of Suni…

Earthi, Mooni and Sunni must have short memories if that happens every time there is an eclipse.

Wow, nice that Ryan has given recognition to the upcoming Solar Eclipse this August 21st!
You lucky people who live in the path of totality are in for a rare treat, as this is a full total eclipse, not an annular one:

And that’s two weeks from today. Please use common sense and just watch it on TV.

Yup. Got my reservations, my picnic basket ready to pack and Plan B, if it’s overcast.

When Connecticut could see an eclipse 20 years ago, I did the paper and pinhole thing, and the moon looked like a marble rolling around on the paper.
The lighting outside was very interesting, like everything was under water.

They do say that the Moon is a harsh mistress. They being Robert Heinlein of course.
